- General purpose small homemade oxygen generator for using in the home workshop. Simple components you can find anywhere make it easy to put together this electrolytic device.
Caution: Do not breathe this oxygen, it is not pure. Usually water from the utilities contains salts which can contaminate the oxygen produced with chlorine! - แนวปฏิบัติและการใช้ชีวิต
I have been thinking of this set up since I was in Junior High School for our investigatory project..Now I know how simple it is...Thank you Chava Tarin.. you're a genius...
Of course, professional help is needed for developing a working project at a high generation level Thanks a lot!
sir..plz give me your contact number.
Ive just completed my first iteration of this generator on a much smaller scale for a small university project and it works great!! just need to play around with my amperage and NaOH concentration within the solution to provide the best conductivity. Thank you for making such an informative video!
Thank God, I am glad I could be of help to you!!! Thanks for your stimulating comment!!!

@@eltunene ils it possible to use this projet d'or patient
Okay, I'm late to the party but you've explained this whole thing so well. I might try making this generator
Thanks a lot for your kind comment!!! Sadly, I think the party is not over yet.
Dear Glanze Epic, thanks for your comment; originally, the project was intended for a small torch, such as the kind used in jewelry. However, it can inspire somebody to keep researching and experimenting in order to produce larger volumes of oxygen. However, several things must be taken into account: Electrolysis consumes a lot of electricity; oxygen and hydrogen must not mix, they are explosive together; large volumes production involves a lot of heat production also, so the materials used must withstand high temperatures: any intention of medical use must be supervised closely by qualified medical personnel, even "known good" oxygen from tanks can be dangerous if excessive; water used in the process must be distilled water, since raw water from the tap may have chlorine salts dissolved as well, yielding to the production of chlorine along with oxygen; finally, if pumps are to be used to try to store the oxygen, they must be special, oil-less pumps, since oxygen is a strong oxydizer, and many objects, including metals, may burn violently in the presence of pure oxygen. Regards!

I think it's awesome that two gases make a liquid! Separate the two gases and they burn but put them together to put out fires! Lol love it
As a matter of fact, Kevin, water puts out fire because water is already burnt. Water is the "Ash" resulting from burning hydrogen in oxygen!

Thank you so much for your easy-to-understand explanation, appreciate your generosity.
Dear Bahman, thanks a lot for your kind and encouraging comment!!!
This is a simple electrolytic separator. An important thing to note is that this process uses a LOT of electricity. It's a very costly process due to this. If you're considering separating out your own oxygen and/or hydrogen to save money, you likely won't. The cost of electricity will likely be more than purchasing the respective gasses from a manufacturer.
Yes, indeed, especially for large volumes, it becomes too expensive.
may be good if u have cheap solar power at home ..
Of course if you provide power from Solar panels you could bring the cost down.
People in India urgently need this!
Thank you on your smart ingenuity of

Water is made of two hydrogen and one oxygen molecule
So when we seperate water molecules we will get the gases in a ratio of 2:1
So we will get 1/3 liters of oxygen from a litre of water

Does it matter what grade of steel you use? In other videos I've heard that low grade stainless steel can produce chromium along with the O2 which is very poisonous. What would be the best grade of steel to use for the cleanest Oxygen?
Mostly i know the solution is using platinum and silver electrodes then potassium hydroxide.

Very good information 👍🏻👍🏻👍🏻👍🏻👍🏻
Thanks, Ginong, for your kind comment!!
I love this project Chava. It's simple and multi purpose. I'll be checking out your other projects too. Thanks,
Thanks, Frederick, for your kind comment!!! The generator was thought for using in a small welding torch, but with certain modifications, it can be used for other applications. First of all, the quality of the oxygen must be much better. Distilled water must be used, so no salts are present, which could pose a danger of producing other gases along with the oxygen, such as chlorine. A solar still can be used to save power in such a process. With regards to the amount of liters of oxygen per minute, that can be determined by the size of the generator itself, and MUST be checked by a health professional. Something else would be the energy consumed by a bigger generator, maybe solar panels can help here.

what about chlorine and other impurities? can anyone provide some input?
@@AlexanderBukh Dear Alexander, using distilled water is a must for obtaining high quality oxygen. Nevertheless, oxygen produced must be certified by professionals in order to be safe. An updated drawing is at th-cam.com/channels/mjQnuJwV0FkjdEyi3099RA.htmlcommunity?lb=UgwRGRtRxJVb63bdsUJ4AaABCQ . Improvements such as adding a solar still for distilling the water, solar power for saving electricity, are shown in this new drawing. I have known of people using the hydrogen to power a gas refrigerator. No amounts nor dimensions are given in this new drawing, since its purpose is to suggest improvements which suit the user needs. I suggest starting small and grow the system from there, using the principle given.

@@jvon3885 what does sun has to do with this?
@@milaanpatel4997 No sun light is needed except to illuminate the evolution of gas on the electrodes.
The outer box does not need to be transparent, either. It can be a clean plastic bucket with a tight fitting lid, which is common all around the world. 1 gallon to 7 gallon buckets are typical in "western "countries.
What if you distill the water (boil-condense) or us an R/O filter to remove all dissolved solids? Then would the oxygen be safe to breathe?
Thanks for your comment! As a matter of fact, You could use a solar still. In my section My Community You Will find a drawing of a simple solar still connected to the generator.

Thank you, Bereket, for your kind comment!!!
Great video. I want to know what is the proportion of caustic soda to be mixed with water. Please share.
A 40% ratio should be fine, that is, 40 grams of caustic soda per liter of water. You can slowly add about 10 grams of caustic soda to half a liter of cold water, then pour the solution into a bigger container, and repeat the operation. CAUTION: CORROSIVE AND DANGEROUS SOLUTION! do not add water to the caustic soda, but caustic soda to one liter of water little by little, since the solution generates some heat and if using a small amount of water, the water can boil and burst. Wear safety goggles and rubber gloves to prevent spilling of caustic soda to your eyes and skin in general. Always use enough water so it can absorb the heat and dissipate it, and add the soda into the water and not the other way. It is better to dissolve a small amount of caustic soda first and give it a try for operation of the cell. You can make the solution in a tall glass of water stirring slowly and adding some grams at a time, handle the solution with care. Do not touch eyes or mouth. On the other hand, the oxygen generated may not be suitable for breathing, due to other salts present in the water. Please check with a physician as to purity of the gas, before attempting to use it for clinical purposes. This project is intended for a small torch, with low volumes of oxygen produced.
Pure h20 is can't pass electricity easily. So it have to do mixed lemon juice costing soda salt anything
i am not criticizing its a good knowledge shared by you.
real world demonstration need.
Thanks for your contribution!!!
Nice illustration, btw, What will be the rate of oxygen flow, ?...litre/minute
Very small rate, since it was thought for a small torch, very small torch. However, with all due precautions, it can be expanded for other applications! Keep in mind Oxygen and Hydrogen are a very dangerous mixture, if you produce a lot of the gases, there is explosion or fire risk.
Wow!! So detailed.thank u for taking the time to make this video.
Thanks, Ann, for your kind comment!!!
Dear Gorilla Disco, the project is for supplying small amounts of oxygen for a mini torch, the amount of hydrogen produced simply goes to the atmosphere, where it recombines with oxygen to form water, ignited by static electricity discharges. It can also be collected and used to feed a propane fridge, however, I omitted this in order to keep the project free from the dangers of hydrogen accumulation and explosion. However, with due precautions, both gases can be stored and used separately.
DANGER!
During the electrolysis of water, ozone is generated at the anode and hydrogen gas is produced at the cathode. While you recognize the flamable dangers of these gasses, you seem to be oblivious to the dangers of ozone. YOU CAN NOT BREATH THIS!! It will damage your lungs. A simple Google search can confirm.
Very fine sir.thank you.also i' am tamilnadu.தமிழ்நாடு.
Can this be used for generating oxygen for medical purpose at home, is it really efficient and would generate oxygen in sufficient quantity
No.... It's not feasible for medical.... U need way more..... That's why they use liquid oxygen
We can use it for emergency, but be carefully dealing with hydrogen, is highly inflammable
Well yes and no, a
Oxygen is not filtered so cant
Great sir
Well I was searching for a solution for oxygen scarcity in India but this method won't be able to provide us much oxygen and the oxygen used for medical purpose is purified and sterilised so its not the optimum one
do we need catalisator? like baking soda?
No, you do not need a catalyst, the reaction takes place as is. What you do need is distilled water, to prevent chlorine from contaminating the oxygen gas.
It's a basic HHO generator, we even did this in science class 40 years ago. Well explained though and nice illustrations, I was just wondering why you didn't have a working model?
My budget is not very fat, and due to health situation, I cannot just go shopping for parts, nevertheless, I already experimented with getting oxygen in the past, when I was a thousand years younger!!!
@@eltunene nevertheless 👍🏻 appreciate your efforts!!
@@eltunene However, if you do not have practical experience, you cannot pretend your fantasies work. First of all, you have the wrong electrodes (screws). Minerals will accumulate on them. After a while, the "screws" will not work (they will not produce gas). A small source of weak voltage and current is more suitable for galvanizing than for the production of oxygen and hydrogen. You cannot absorb hydrogen in the free space of the box, but in the bell, as you have with oxygen. Replenishing water with a "toilet" mechanism is very optimistic - you probably expect a large production of gas, but this is a complete mistake. If you industrially produced hydrogen by electrolysis with a power input of several kW, it would be understandable. In the domestic embodiment, the water is replenished through connected vessels, i.e. by another "toilet" mechanism. It is also necessary to make the water conductive, preferably table salt. My hydrogen and oxygen (Brown's gas) generator has the right design and power source. It can continuously supply a small burner with which it melts glass.
It's electrolysis of water. HHO generators are a BS gas mileage scam device.
@@loctite222ms Scam device? They aren't a scam device to be honest, but yes plugging one into your vehicle and expecting it to power it is a pipe dream. The process of separating hydrogen and oxygen from water is a real thing.
An excellent presentation. Thank you sir.
Thanks, Mahmood, for your kind comment!!!
@@eltunene You are most welcome Mr Chava Tarin.
Great for producing very small amounts of gas, but if you want more volume I suggest using a whisk with copper scrubbers stuffed inside as your electrodes. They will provide far more surface area for electrolysis. Also, oxygen isn't just a good oxidizer, it is the ONLY oxidizer.
Thanks, Harold, for your contribution!!
@@eltuneneI Think the best should be inox!! copper or most of others metals ends by giving rubbish in electrolite! Never pleasant to clean and refill!
Why not use stainless scrubber pads 8n the wisk?
@@superjeffstanton Good idea! The copper does exude some nasty particulates over time.
Fluorine gas or chlorine gas are also oxidizers , much stronger than oxygen and thus not existing in free gas condition in our environment.
Can we make it for patients..?

Great job you doing great
Take care 🙏🙏🙏🙏
Genius Chava Tarin! Thank you.
Thanks, Alex. As a matter of fact this method for obtaining both oxygen and hydrogen goes back to the nineteenth century.
My school buddies dad had a machine in the back of his muffler shop that used this process to make oxygen. The machine looked very old in the 70’s so I would guess it would have been made in the 1920 to 1940 era. It took up about a 6 foot long bench. Just electric and city water hookup. He never had to buy oxygen for his shop. Plenty of pressure to run a cutting torch.
Thanks for sharing, Dan, indeed it's an old technology! It is a good practical way to generate oxygen, with the convenience of solar power, it becomes more and more inexpensive every sunny day!!!
Thanks for your good video..
But can you tell us how many NaOH% must be mix with the water %.. thank you
Nice to know.
NaOh acts as electrolyte to conduct DC current through water. The percentage is usually decided by current limit of power supply, but not everyone will have multimeter at home. So eyeballing the bubble and wall socket temperatures works just fine. If you add too much you will burn the wall socket.
For practical purposes. Start with very little until you see bubble rising, and then keep adding until you see whole screw covered with bubbles. Keep and eye on wall plug temperatures every 5 minutes, warm is ok but hot is not. If you add too much NaOH you will burn the wall socket.
Muy bueno. Explicación simple y clara. De joven, muchos Experimentos así, realicé.

Electrolysis is also very good for removing a rust from a steel, iron etc

I just want to ask one thing, what the he'll are we drinking it's either oxidizing us or blow us up ?
Thanks, Neil, for asking that question!! Water will not blow us up since water is the product of combustion of hydrogen in an atmospehre of oxygen, thus water is already "burnt up" in other words, water is the "ashes" of burining hydrogen in oxygen.

So the +ve terminal electrode generates oxygen?
Yes, it does. It does not create it, but it takes it out of the water, and at the same time, the negative electrode releases hydrogen.
Well, done. Informative and useful, thank you.
Thanks a lot, Pistolero, for your kind comment!!!
In laddhakh where is more snowfall situation when start
Very good explanation.👏👏 Can we also use a full wave rectifier? Do we need to pour more NaOH after sometime? How much dc volts are necessary if we want to use this for medical purpose for one person?
Dear Santosh, thanks for your kind comment!! The diode bridge IS a full wave rectifier. If no contaminants get in the tank, no more NAOH is necessary. The amount of DC volts is determined by the medical professionals, depending on each case. However, if your application involves a human life, a qualified physician must check the quality of the oxygen being produced, as well as the quantity. This project was suggested with the idea of using in a non-critical application, for medical purposes, qualified assistance is necessary!

Dear Mayur, this suggested project is by no means a new invention, obtaining oxygen from water is a very old system, as early as the nineteen century, used at first to measure electricity (hofmann voltameter), and later for torch welding. However, a formal project could include a solar water still (to get pure distilled water), and solar panels for the electricity source. Please follow this link to a drawing I made illustrating improvements and updates for a more practical system. th-cam.com/users/postUgwRGRtRxJVb63bdsUJ4AaABCQ .
Do you need to replace the sodium hydroxide? I assume not.
The sodium hydroxide is not lost in the reaction, so you are right, no replacement needed. However if solution gets somehow contaminated, you may have to replace the solution entirely.
@@eltunene that’s interesting, is there any way that you can tell it’s contaminated?
I think there is a big mistake here: *ONE* screw only? there in no surface area there, it will only produce a minuscule qty of O2, no? Thanks
edit: i went back,and you did say that the surface area may need to be increased; anyway,that is the principle,and needed cautions, good video.
You´re right, the larger the area the more contact with the solution and the higher the amount of O2 produced. The problem is if oxygen is too abundant, there is the risk of a fire. Anyway, the principle is valid for bigger plates, generator cells and amount of water. You can even work with much higher voltage than the one I suggested, and get several liters of oxygen per minute.
@@eltunene several liters? i didn't know that,i thought you'd get much less; i will try that,i need a oxy-propane torch; but i do not want accumulation of that H2 anywhere,not even on top of the water either,may have to use a second bottle for that,vented to the atmosphere thru a just enough thin hose.
@@josepeixoto3384 Good idea! If you use separate hoses, maybe it will even work by feeding oxygen and hydrogen to two nozzles separately, and replacing the propane by hydrogen. By using larger electrodes, and maybe a higher voltage, you can get more hydrogen and oxygen (separately, in two independent hoses. You can build it differently by using two cells for oxygen and hydrogen, using PVC pipes. One basic thing to keep in mind is to leave the PVC open in the bottom and the electrodes at the proper position in order to have the liquid down until the electrode is not making contact with electrolyte at all, so the reaction will stop when the PVC pipe is almost full with gas. This will insure the reaction will stop and the gas wo'nt "spill around" the electrodes, allowing both gases to mix, which will not be safe at all.
Covid patients ke liye use kar sakte?
if positive electrode change to a bigger one, get more oxygen than hydrogen??
Dear Anjaly, water is made of molecules containing one atom of oxygen and two atoms of hydrogen. When electricity separates them, you get one volume of oxygen and two volumes of hydrogen, all the time.
@@eltunene thank you
@@eltunene I don't think so, the quantity of H2 is twice O2 provided that the two electrode are the same, otherwise the O2 quantity are bigger if the positive electrode is bigger than negative.
cant you use the hidrogen as natural gas?
Yes, it can, as a matter of fact, it is being used to power automobiles and power plants. However, in spite hydrogen is the ideal fuel, since it just produces water and no carbon footprint, some technical difficulties must be overcome, mostly related to safety. Hydrogen is odorless, so it cannot be easily detected when there is a leak somewhere. Production is still more costly than merely extracting natural gas. Hopefully, the situation will change and people starts using more alternative sources for power. But, yes, hydrogen produces a very hot, almost invisible flame.

Estimable amigo ¡muchas gracias por su amable sugerencia!
This is simply great.🙏🙏🙏
Excellent video, is the NaOH consumed in the process and should more be added occasionally?
Dear Groovy One, the NaOH is not consumed in the reaction, only if it gets contaminated by some scale in the water, it must be replaced, water and all. By using distilled water, it yields clean oxygen, however normal tap water does contain some salts that might pose a risk of oxygen contamination with chlorine. Very important, both gases must not mix, since the mixture is very flammable! Also, some heat is evolved in the process, so cooling may be needed. If you plan to build it, please start with a small version, and go on from there, either by enlargement or by using two or more small units in parallel. I have heard of someone using the hydrogen for running a gas refrigerator, which would make good use of the otherwise lost hydrogen. Oxygen must be certified by professionals, to make sure it does not contain toxic gases, such as chlorine! I also posted an Indi version, and at the very end there is a scheme with some suggested improvements, please take a look at that too.
@@eltunene Thank you for your reply, I don't intend inhaling the oxygen so no concerns regarding impurities. What I would like to experiment with is using a 200W 20V DC solar panel as the electrical supply for electrolysis, running both H and O gasses through separate tubes running directly into the carburetor of a small 700W 240V AC generator. I'll start it using petrol then when it's running, turn on the gas and turn off the petrol and see if it continues to run.
Can we use this to fill oxygen in cylinders? Helpful in medical field now especially at places like Brazil where people are in high need for oxygen cylinders to fight covid.
Dear Justin. This suggested project is by no means a new invention, obtaining oxygen from water is a very old system, as early as the nineteen century, used at first to measure electricity (hofmann voltameter), and later for torch welding. However, a formal project could include a solar water still (to get pure distilled water), and solar panels for the electricity source, as well as special pumps to store the oxygen (and the hydrogen) in cyliners for later use. Please watch this video by a fellow youtuber th-cam.com/video/DFf0vP3Dtb4/w-d-xo.html and this article in Wikipedia en.wikipedia.org/wiki/Oxyhydrogen . By combining the oxygen cell, a solar still and photovoltaic electricity, large volumes of oxygen (and hydrogen) can be achieved at a low cost.
One of the problems that you can have is the chromium in the stainless steel that it is released as a result of the corrosion of the screw. Maybe, it is necessary to put some filters to clean the air and make some measurements.
to clean the oxygen
The ocean, the poles, the earth.
it is use for covid Patient?
For that application, you MUST have a health professional check and certify your oxygen. If water used for the solution contains any salts or scale, it can produce chlorine along with the oxygen, which is toxic!

There are a hundred different tutorials on how to make one of these, just look up Electrolysis or HHO Generator. Only difference between this one and those is this is focused on collecting the oxygen while an HHO Generator is focused on collecting both while mainly producing larger amounts of hydrogen.
@@b-rad7708 regarding medical purpose, the hydrogen will have to be oxidised at generation to create water vapour, so it does not get explosive.
That way the product will consume atmospheric oxygen and give out pure oxygen.

Dear Richard Pagan, I just uploaded a video in Hindi (machine translation) please check it out and give me some feedback. People in India are very creative, they can improve the generator to suit their needs!
What if I use 110V AC directly to a 600V rated Bridge Rectifier instead of the 24V that you are demonstrating to generate O2, would that produce more O2 and HH2?
Dear G RP, you are right! The more the energy, the more of both gases you get. However, you must exert some caution and proceed by gradually increasing the power applied to the device, since some heat is also generated. Maybe you could start with a smaller amount of NaOH dissolved in the water and watch for overheating of the solution (by disconnecting the power before checking the solution temperarure). You could also add an external limiter, such as a light dimmer you can turn back and reduce the amount of energy flowing through the cell and thus control the reaction. Please be very careful to check the two gases do not mix. Please let me know about your results.
@@eltunene thanks for the quick reply! That's a great idea using a limiter on the supply voltage and gradually increasing it. I'll use my thermal gun to monitor the temperature. I will let you know the results. Cheers!
Oxygen amount generated is proportional to the current in amperes or coulombs. So higher voltage doesn't mean high amount of oxygen, but making heat. The best is using a variable dc supply has voltage and amperage indicators.
But what material is the oxygen and H2 gas contained in the tank? thanks just help
Kindly specify how much oxygen will be generated .will it be sufficient to treat Kovid patients.
Dear Avinash, The amount of oxygen generated depends on the size of the cell, as well as the amount of current available. The main thing is to make sure the oxygen is pure, and that can only be evaluated by a qualified health professional. Please try with a small device first and check the quality of the oxygen produced, if this is correct, you can expand the system, always keeping in mind that hydrogen and oxygen must not mix in the machine, since they are an explosive mixture, and also the reaction involves a small amount of heat, so you must check for that also, if the machine becomes considerably large. First of all, oxygen quality and secondly, check for heat generated. I have a drawing with suggestions, no amounts or sizing specified, but the main features such as layout and electricity sources. This drawing is at my community.
@@eltunene thanks
Dear Christoper Eduardus, some gases are commonly found at standard temperatures and pressures as diatomic molecules, such as hydrogen (H2), nitrogen (N2), oxygen (O2), fluorine (F2), and chlorine (Cl2). Other gases, which have their outer orbit completed, such as the rare or noble gases, exist as monoatomic molecules, these are are helium, neon, argon, krypton, xenon, and radon. Oxygen and Hydrogen, when separated from their compounds, naturally assume their diatomic molecule structure.
Hola Cahva Tarin, siempre pensé, si hacen celdas de hidrógeno, ¿Por qué no usar también el oxígeno?, Gracias, muy buena explicación. Anita
Gracias, Anita, por su amable comentario!!!
Overall is very good.
Even Though I just understand english a little.
I Understand this design.
Video itself helpful to understand the instruction.
I wait your next video
Thank you very much CHAVA TARIN.

Dear Ismoyo, thanks for your kind comment!!
Wonderfully explained, thanks.
Looks like toilet tank can be altered to fit this setup?
Can it generate oxygen fast enough to help a covid patient ?
Dear Shirish, it can be possible to generate oxygen as fast as you want, however, beware, there are some other vital concerns. If water from the tap contains some foreign substances such as sodium chloride and other salts, as well as chlorine in solution, the oxygen can be badly contaminated by chlorine and other lethal gases. On the other hand, only a doctor can determine the rate the patient needs. Another high risk is handling both oxygen and hydrogen, if a considerable amount of oxygen is present in a room, virtually any object becomes violently flammable, such as drapes, fabrics, plastics, even some metals can burn in a pure oxygen atmosphere. Other than that, the bigger the generator, the more gases produced. Using stainless steel plates instead of screws, a bigger power supply and a bigger piece of equipment, you can get any amount you wish.
Hello, change the stainless steel electrodes to avoid Hexavalent Chrome, change them for titanium, platinum or graphite (the cheapest).
For electricity use a source with more amps like the battery of a motorcycle or vehicle, with voltages between 12v will give you good results.
Add a bubbler to the oxygen outlet to add moisture.
Be careful with the duct that carries oxygen, check that it does not have water drops because it contains caustic soda, it must be dry inside the duct.
Use distilled water to avoid impurities.
--------------------------------------------------------------
Hola, cambia los electrodos de acero inoxidable para evitar el Cromo Hexavalente, cambialos por titanio, platino o grafito (el más barato).
Para la electricidad utiliza una fuente con más amperios como la batería de una moto o vehículo, con voltajes entre 12v te dará buenos resultados.
Agrega un burbujeador a la salida del oxigeno para agregarle humedad.
Ten cuidado con el conducto que lleva el oxigeno, verifica que no tenga gotas de agua por que contiene la sosa caustica, debe estar seco al interior del conducto.
Utiliza agua destilada para evitar las impurezas.
Yes. Fast enough to burn his lungs.
This ^^^ or maybe in future on other planets where no oxygen is present 🤔
It use water?
For the original application as a very small torch oxygen source, plain tap water can do. For more stringent applications, distilled water should be used.
Perhaps you could store the hydrogen too and sell it later for electric cars. Good business.
Hydrogen when compressed is dangerous. If it's not pure it explodes.
Yes hydrogen can be stored however the cost of cleaning, compressing and storage make burning wood more efficient than hydrogen.
How much will it cost totally?
Prices are going up in all things, I built it long ago, so I have no idea.
built almost this exact same generator on a smaller scale for less than 50 bucks in total
can you list the parts i need to buy to make this
Dear Wilfredo, the parts are not critical, for instance, the tank is any plastic box, preferably clear, the piping is normal PVC used in home for bathrooms or kitchens, the power supply can be just a transformer and four diodes, however, you can test it with your car battery (beware of polarity, so oxygen comes out of the right pipe). The stailess steel screws can be replaced by stailess steel wool, for a larger electrode surface. As a matter of fact, the first part of the video lists the suggested components, but they are not limited to the dimensions listed. Just keep in mind oxygen and hydrogen are very dangerous, since if ignited, they combine violently. Keep all connections airtight.

What did you do with the hydrogen?
3:32 the word "i guess" threw me on the floor and made me laugh uncontrollably.
The intended word was "a gas", not "I guess". Sorry for the accent!
I think you also see it in TH-cam captions 😀
stupid monolinguals...
Once used sodium hydroxide will give continue oxygen? If water supply is constant by valve.
Dear Abbas, yes, sodium hydroxide does not get "used up" in the reaction, only water does. As long as no contaminants get into the solution, sodium hydroxide does not wear out.
Hello.please i have a question. Can i get a pure medical O2 from the electrosis process?
Dear Poly, yes, you can, but it all depends on the purity of the water you are using. If the water contains traces of a chlorine salt, such as sodium chloride, this can yield to the production of both chlorine, a toxic gas, mixed with oxygen, which is not good for breathing. If you can used distilled water, you can indeed get pure oxygen. Once you are getting the oxygen, please follow all precautions related to the danger of handling oxygen and hydrogen, which are an explosive misture. Also, a qualified phisician must check both the quality of the oxygen produced and the amount needed by the patient, which can be easily adjusted by sizing the electrolytic device properly.
@@eltunene dear chava thanks a lot for your precious ansewer.i will follow this method.and keep you posted.my best regards
Dear chava. What about if i add caustic soda to water the sodium hydroxide dont make any gases i think?so my o2 will be pure. Thanks a lot.

Do you make kits to buy?

Please take a look.
Good presentation... but pl. Can you try to explain practically rather than theoratically?
Dear, Can I use 300V DC? No need the 24 VDC? Thanks
Dear Chuong, you may, but must consider the fact that some heat is produced during the process. The higher the voltage, the higher the gas production, but also the current will be higher and the heat evolved can damage the components of the tank. Please contact qualified personnel as to high power components for electrolysis. Also, the plastic parts must be more resistant and the seals between fittings must be high temperature resistant. Any leaks and mixing of the gases can be disastrous!
@@eltunene Thanks
@@eltunene Yesterday, I tested it. The temperature is high. But I do not know why there is little O2. I will add more baking soda into water today. Do you think it is ok? Thanks a lot
Good enough, but production can be doubled by making the anode from aluminum metal and using dissolved (in water) sodium bicarbonate instead of aquious NaOH.
man can u tell how or link a site which explains this im very curious to know bout this ))
@@harekrishnaparhi7943 Just do it, you'll see, but DO NOT test with an open flame? You've been warned.
El bote donde se genera el oxigeno tiene que estar perforado de abajo ? , Increíble video , the bottle that contains the positive pole need to be perforated in the bottom?
¡Exacto! Es una variante del voltámetro de Hofmann, que originalmente se usaba para medir la corriente eléctrica, y después para demostrar la electrólisis. Estando el bote con el electrodo a cierta altura, el oxígeno permanece sin mezclarse con el oxígeno, y sale por la parte alta del bote. ¡Saludos!
THANKYOU OLD MAN!!!
Thank, you, for your kind comment!!
If someone comes at your house and switches the polarity of the system, you got a Big Bang House :)
Yes, hope nobody does that!
