Wow. Amazing Explanation. I wish my textbook was as elaborate as this video lecture.
you all probably dont give a damn but does any of you know a tool to log back into an Instagram account..?
I was dumb forgot my login password. I would love any assistance you can give me.
@Torin Adrian instablaster =)
@Jasiah Christian I really appreciate your reply. I found the site on google and Im trying it out now.
Looks like it's gonna take a while so I will reply here later with my results.
@Jasiah Christian it did the trick and I finally got access to my account again. Im so happy:D
Thank you so much you saved my ass :D
@Torin Adrian Glad I could help xD
Thankyou so much, this is really helpfull,
Thank you i love the wat you explain
When I was in 8th grade I used to think 9 volt batteries contained fluorine, because only fluorine could give such a high oxidation potential! It didn't occur to me that 9 volt batteries had multiple cells.
ur 8th grade teacher be rocket scientist
In my 8th, i hardly know what exactly voltage means😂
and it took me 3 years to figure out how to get to the 9th grade
In 8th grade i was still drinking milk
Wow amazing sir!!!!!!! 😀😀😀😀
I swear this guy knows everything 🙆♂️
I love your videos they helped me out a lot I just hope you could just speak a bit louder i love the calm voice but honestly I find it hard to hear and have to replay some parts a couple times
Thank you 💕
Love it. Thank you for video but have a few questions:
What is the best way to extract the NaOH solution (separating it from the existing NaCl)? Or do we need to completely electrolyze all the NaCl to yield NaOH.
Similar question H2O2, how do we extract and keep it from reverse reacting back ot H2O and O2? Just keep it really cold but not freeze H2O?
when i get my bachelor im gonna credit this guy
Thanks for your clear explanation you got me out of swampy, murky,muddied-water.
You ain't y'a
What happens in neutral conditions, to electrolysed sodium chloride?
What type of anode and cathode do I need to generate chlorine dioxide from sodium chlorite?
You saved my life. My final is on Monday and my prof did a terrible job explaining electrolysis.
You saved me.
Will products at electrodes same amount or different amount
Thanks for you 🌸
So what happens if I use copper electrodes in NaCl electrolysis?
Just like NaClO3 can we make NaClO2 using Hot Electrolysis method ??
bro has an explaination to everything
Dude electrolysis is supposed to breakdown the compound into individual components. If its an electrolysis of NaCl we should be getting individual Na and Cl particles but we've ultimately just broken down HCl (under acidic conditions) and water (under basic conditions). We didn't separate the NaCl components
Hello.. Bro... How can we do the electrolysis of molten aluminium sulphate??
for effective electrolysis of NaCl solution you need an ion exchange membrane between electrodes that allow only anions or cations to pass
Good
Sir please what is the function of the electrolysis series of reactions
But H+ doesn’t exist independently in solution. It’s H3O+ that exists which gets reduced. I don’t know why textbooks always include H+ when it doesn’t exist spectroscopic studies have proven its H3O+. Appreciate the way you explained oxidation half though.
Its the same thing... H3O+ happens only because the hydrogen ion is in an aqueous solution
is there a chemical reaction that reacts to saltwater and produces water and a non-toxic precipitate in the end (or toxic/non-toxic gas)?
now you're onto something here
why do we also have HCL?? if nothing indicates that there is HCL then should we assume there is
2nacl +2h²o..E...... >2naoh+cl²+h²
naoh+cl²........>naclo+h²o
12:15 where goes oxigen of h2o ?
to hydroxide OH-
How did you know this concept.
At 4:39, how come the two oxidation potentials do not add up to -1.23V?
Good question I hope someone replies to this with why
Why does the concentration of hydroxide ions increase?
Am I understanding correctly that the acidic and neutral solutions become more basic as NaOH is produced? Does this mean a neutral solution will in the beginning produce Cl2 but after a while produce more O2?
I think it does.
Thane has a product that electrolyses salt water to produce HClO and also NAOH, I dont' believe that your video accounts for the production of sodium hydroxide, so how does their product cause this reaction ? Maybe one electrode is a special catalyst?
for effective electrolysis of NaCl solution you need an ion exchange membrane between electrodes that allow only anions or cations to pass
and choosing the best electrodes reduce side reactions
Electrolysis of a mixture of Sodium chloride and water →???
Hi, do you know at what concentration oxidation of chlorine is favoured to oxidation of oxygen
One question that bothers me all day ;
The battery cell is a galvanic cell, which means its Cathode is the positive terminal. The Anode is the negative terminal
But in electrolysis cell, the Anode (battery) change to be the positive terminal, while the Cathode (battery) turns into the negative terminal
If i was correctly, about the symbol :
🔋🔋🔋the short one (battery) is Cathode, while the longer one (battery) is Anode.
Dear Sir
Could you please provide me with the electrical and mechanical design to the cell membrane type to produce NaoH with arate of production 50 leter/ hour design concentration According to economical state.
Thank you
womp womp
I have an doubt:
The anode is always placed on the left side, and the cathode is placed on the right side but why you did it opposite?
Please answer my question
7:24 by hoping same thing i made an experiment setup i used one bottle filled with nacl and water with electroads in it and attached pipe by silling it and i dipped that pipe in other bottle filled with water hoping that , H from negative and cl gases From positive terminal will produce and and because both makes hcl and after desolving it in water bottle i will get hcl acid , i lived it for 2 days but i did not geg any meaningful evidence of hcl:h2o solutions !! Then thought may be there would oxigen which are interfacing with cl may be !! But after watching your video i knew probability will be very low for oxigen !
But m not sure plz tell me what is wrong with mine setup ?
I used near 600ml watef and 3 or 4 "suger spoon" of nacl table salt ! And i also added h2so4 will it help to produce hcl ?
reacting gases directly under a saturated fiberglass tent(small volume!), or sum saturated substrate that wont react with HCl might work. careful, gasses will react with light to recombine and explode as electrolyzed H & O reacts with spark to recombine to water with extreme heat; they(water electrolysis cells) have been made into torches that can cut firebrick and weld steel but curiously won't heat water itself, so you can't burn your skin which is mostly water. but HHO gas can explode and f up your world if you try to store any substantial quantity and H & Cl only need light radiation to recombine and the energy of recombination is even stronger if i remember correctly; H & O need at least a sparc of 12mJ to recombine. note that there were experimental rocket engines using HCl and the energy of recombination produced blasts of mac 7 supposedly.
I really wish I never tool igcse
Thanks, now I can make an explosion :D
How is the pH=0? It can't be as that's extreme acid.
Hello ph -1 is possible
@@dr.jayanthikumaresan9106 Thanks. What you say is correct.
Dude it’s salt
That's what i said
you're supposed to push the buttons with the pictures of food on em
No dude it's NACL or tata salt or urine salt
No shit
pure NaCl actually differs from table salt because in table salt there are tiny amounts of iodide that are added
OK, not quite correct as to likely mechanics (which not addressed in summary electrolysis presentation. Now, H+ (from water leaving alkaline OH--)+ e- = . H (the hydrogen radical anion). The latter can self react: .H + .H -> H2 or, to a lesser extent, react with O2 (also produced in an over potential electrolysis of water) as follows: . H + O2 -> .HO2 but at pH over 4.88 exists as H+ + .O2- (the so-called superoxide radical anion). Bottomline, no H2O2 which could otherwise be created in the albeit slow reaction .HO2 + .HO2 -> H2O2 + O2. Also, no H2O2 in the presence of NaOCl or HOCl (from Cl2 formation of aqueous NaCl electrolysis) from the fast reaction H2O2 + HOCl -> H2O + HCl + O2.
shouldnt be the potential for 2Cl- to Cl2 + 2e- be POSITIVE 1.36?!
👍👍👍
🎈🎈🎈
you forgot to add the potentials at the end dude
WHY DO WE USE OXIDATION AND REDUCTION POTENTIAL IN AQUEOUS NACL...WHT IS THE NEED BEHIND THIS
PLZZ.... MAKE MY ANSWER TO BE CLEAR
I have sn exam in 5hrs
ｗＯＷ
brooo thank you for the effort but come on sooo sloowww repeated 100 times keep dazing off but again thank you for your time
set the video to 1.75 speed, it's much easier to listen to
