Bro you are the best, i would suggest a channel rename because you are basically explaining everything, you don’t want people skipping your channel because of a misleading name! Cheers!
Professor Organic Chemistry Tutor, thank you for a beautiful Introduction into Electrolysis of Water in AP/General Chemistry. The electrolysis of water results from a transfer of electrons and the release of hydrogen and oxygen as gases. This is an error free video/lecture on TH-cam TV with the Organic Chemistry Tutor.
3:05 should be “electrolytical cell” rather than “electrochemical”, but other than that this is the best explanations of electrolysis I’ve seen! Thanks!
Thanks JG. This video is a great explanation to understand Electrolysis. Btw, the standard electrode potential for 4OH- >> O2 +2H2O +4e- is the positive 0.4V. The electromotive force (E0) for electrolysis is -1.23 V which is calculated by (-0.83) - (+0.4). E(Red) - E(Ox). Looks you add (-0.83)V and (-0.4)V to get -1.23V but I think (+0.4)V is correct.
In case if u r wondering about the equation at anode: OH^- = OH + electron OH^- = OH + electron OH^- = OH + electron OH^- = OH + electron There fore the overal equation at Anode is 4OH^- = 2H2O + O2 + 4electrons
@@VanisyJonathan i thjink he means whjen you add the products together from top to bottom row it forms the final equation 2H2O O2 + 4 electrons where there are exactly 4 H 4O and 4 electrons
@@isaacmolina5500well it's just the properties of the stoichiometry, you can see that in the product side of the reaction (right side) there are 2 molecules of H2O and 2 atoms of oxygen. Which means that in total there would be 4 atoms of hydrogen and 4 atoms of oxygen. Therefore, to balance the equation it needs to be the same amount on both sides. Since on the reactant side there is only a hydrogen atom and an oxygen atom we put the stoichiometric coefficient in front of it, making it 4OH
12:44 I disagree. The reaction does not occur unless the activation energy is provided. The bonds of the Hydrogen molecule, H2, and Oxygen molecule O2 must first be broken before they are free to combine. The molecules will not slowly accumulate energy until there is enough to break the bonds. Wayne Y. Adams B.S. Chemistry M.S. Physics
is it the current or the voltage that breaks the bonds, i was thinking maybe you could have two or more cathodes connected in a series or parallel circuit 🤔🤷♂️🙇♂️
Cathode = Reduction both start with consonant. Anode = Oxidation, both wowels. Thats how I still remember it after recieving my diplome 19 years ago. ( I'm a chemist, but work on completely other field, nothing with electrochemistry...)
Ok so I'm seeing the Mr.JG is only crossing out elements and electrons which are in the different sides of the arrow. So is that some kind of rule in that we can only cross out stuff is they are present in both half reactions if we need a full reaction?
correct, numbers of H and O should be the same, as well as the charges on both side of so called " half- reactions". If you sum up anode + cathode xou get decomposition of water to H2 and 1/2 O2.
the standard potential of anodic reaction is greater than cathodic rxn then it should be then reduction not oxidation like cu and zn zn have -0.76 E and cu is 0.34 E so reduction of cu occurs. then why in case of water the less E value is reduction. can u plx explain it
If you are open to doing personal tutoring please let me know. I have a 6 week organic chemistry course coming up and I know its going to be extremely difficult to do a class like that in 6 weeks. I am willing to pay. Thanks in advance
I can't understand the role of the electrolyte. I mean it is the water that splits into the components. Why the movement of the electrolyte "helps" electrolysis? I mean what if we haven't any electrolyte? At the cathode water molecules could still take electrons and at the anode water molecules could still give electrons.

I'm curious what material do you use for the cathode and the anode are they different other than the positive and negative?
if I accomplish anything academically in life I will owe a solid amount to you and your videos, thank you
Like I will never forget him seriously
Well have you?

nope, +0.4 V is not correct. I think he reversed that equation with +0.4 V to get - 0.4 V.

Because at this point youve gotten me through way more than organic chem
Nice Video. Quick correction at 2:34 - should be 2H2O + 2e- -> H2 + 2OH-
Zach Kelly where does the OH from?
hi! i was wondering why the reaction at the cathode is 2H2O + 4e --> H2 + 4OH
why not 2H+ + 2e --> H2?
thank you🙌
that was a thumbs up, this is awesome. i love the video and the explanation
I understood carefully.
Thanks.
Student from iran.
Learnt more in 13 min than I did in 6 classes. Fucking good video
Definitely watch playlist of oxidation and reduction including balancing to easily understand
Nobody has explained this better. :)
Am always happy to watch your vedio. Have learnt so much from you thank you so much
thanks a lot , it really helped me understand the concept
In case if u r wondering about the equation at anode:
OH^- = OH + electron
OH^- = OH + electron
OH^- = OH + electron
OH^- = OH + electron
There fore the overal equation at Anode is
4OH^- = 2H2O + O2 + 4electrons
Where do you get 4 OH^- from?
Yes where did you get it?😢
The way u've explain was not clearly way

Great video. Explained it perfectly
We can’t even thank the ACTUAL NAME of the owner of this Channel! but thankyou anyway ✨ I salute you, JG(?) perhaps. i

A education program should give you accreditation!! Better than my college professors!
I don’t think you mentioned the concentration build up of heavy water at the bottom. It’s small but still worth mentioning.
Thank you so much for covering so many topics. It was hard to find a video specifically on the electrolysis of water.

Very brilliant video. Thanks.
Good work really helpful ♥️
Hi could you explain the plasma electrolysis of water as well? I could not find enough information on that. Thanks!
yo shoutout to man, you make so many videos
This guy helped me so much.
Awesome 🎉🎉🎉
you are the best of all
10:44, 2H2O --> O2 + 2H2
but yes, he has corrected it.
Good explanation
How is the reaction described in the video an example of an oxidation/reduction reaction?
Very good 👍 👏 👌
Great stuff!
i used to do this as a kid with jar with a nail & a carbon rod from a dead battery with salt water
Dods it produce pure oxygen at the anode.
Im confused by the + 4 electron
2:14
In electrolysis you will get only pure elements as the products .
So after electrolysis will some sodium metal be seen on the cathode?
U r just the best 😘
What is the best electrode and what to do to increase the rate of reaction
add sodium hydroxide
Nickel {catalyst}
Can you explain me more why oxidation pair of OH-/O2=-0.43v became oxidize and H2O/HE=-0.82 became reduced?
I just don't know how to thank you again 🤗💥
youre my lifesaver
😂 how about God now who is to you!?
Can you kindly explain if we use NaHCO3 instead NaOH? I do want u to help. Thank you
We need to separate hydrogen from oxygen in the air
Heatwaves are partially from vapour build up in the air
is it the current or the voltage that breaks the bonds, i was thinking maybe you could have two or more cathodes connected in a series or parallel circuit 🤔🤷♂️🙇♂️
So, the most easily oxidized species reacts at the cathode? That's where I'm confused
Cathode = Reduction both start with consonant. Anode = Oxidation, both wowels. Thats how I still remember it after recieving my diplome 19 years ago. ( I'm a chemist, but work on completely other field, nothing with electrochemistry...)
@@gergokovacs3332 Red cat and An ox ( the animal) Is how I remember
2:37 There are mistake , instead 2H2O ,there should be 4H2O. One more mistake at 10:44 instead 2H2O ,should be 2H2
He didn't just balanced it, not a mistake
Ok so I'm seeing the Mr.JG is only crossing out elements and electrons which are in the different sides of the arrow. So is that some kind of rule in that we can only cross out stuff is they are present in both half reactions if we need a full reaction?
Thankyou 🥺🙏🏻
Is it possible to find self potential list for all elements in my old chemistry book? Or somewhere on internet ?
1:11 I have read that an acid is used in electrolysis and NaOH is a base. So will it work??
Alkaline solutions can also work as they can conduct electricity
That was pefect video
Teach me more I need this on our research
ano research nyo???
@@waffles9771 hi bakit may pinoy dito
Guys watch physics wallah in hind the best and amazing teacher not on TH-cam but from whole world love you sir❤️❤️❤️❤️❤️❤️❤️
I’m a bit confuse, hydrogen has reduction potential = 0. Should it be Hydrogen at cathode instead of H2O?
H20 has more reduction potential than H2
Thanks a lot!!!
Plz tell me , which is the best catalyst to do that ? Can i use sodium bicarbonate?
After continue watching i found it's similar to that i am looking for ? But still wanna know about baking powder ?
Use salt
thank you, I want to ask about hydrogen at the cathode ore anode because I am confused
nicely done
what is this apps name that ur using to make us understand electrolysis i wana download it
tell me
Bro you didn't uploaded kolbe's electrolysis reaction in the channel yet....
Very helpful video thank u
i cnat quite seem to understand why is it exactly the otherway around in a electromachnetic cell ( cathode is postive anode negative)
How much time does it take ???
thank you very much
I am not sure about the reaction at cathode, Shouldn't it be 4 H2O + 4e- → 2H2 + 4OH- ?
correct, numbers of H and O should be the same, as well as the charges on both side of so called " half- reactions". If you sum up anode + cathode xou get decomposition of water to H2 and 1/2 O2.
Next video, 'How to store hydrogen.'
Which board you use
Plz reply
isn't the cathode supposed to be the positive side and anode the negative?
Which app are you using for the writing reply pls
So what experiments can one do to prove that gases are originating from the water and not the electrodes or electrolyte?
Best period
Thanks
the standard potential of anodic reaction is greater than cathodic rxn then it should be then reduction not oxidation like cu and zn zn have -0.76 E and cu is 0.34 E so reduction of cu occurs. then why in case of water the less E value is reduction. can u plx explain it
How do you get the negative volts
How can i know that a metel should be written at the cathode or anode?
What is the name of the application used to "black board write"?
why is OH oxidizing
sir i think the anode should be on the other side
and the cathode on the other
or maybe its how you draw the battery
H202 is peroxide, and h20 is water right?
good video but you miss to explain why eletrode wear out in this process
i love you bro
nice vid
since you started with NaOH doesnt that mean that reaction that you said was not likely to happen already happened?
I think he was talking about removing OH from the water
Why does the less reactive one get discharged on the cathode?
it’s been a year💀 but the more reactive a metal is the more it prefers to stay as an ion and not get discharged
After Electrolysis, what happens to the water. they change the water in a particular interval.
If you are open to doing personal tutoring please let me know. I have a 6 week organic chemistry course coming up and I know its going to be extremely difficult to do a class like that in 6 weeks. I am willing to pay. Thanks in advance
2H2O + 4 e- is H2+ 2OH (not 4 OH) . Am I right?
yes, except 2e not 4e on the LHS
I can't understand the role of the electrolyte. I mean it is the water that splits into the components. Why the movement of the electrolyte "helps" electrolysis? I mean what if we haven't any electrolyte? At the cathode water molecules could still take electrons and at the anode water molecules could still give electrons.
But why the long side for positive?
How does 2h gives off for storage
What happens when you run out of water? There is just NaOH left, and it starts to form elemental Na?
Yeah, that's a really good question. If all the water is lost in the processes, what happens to the sodium?
Lets say you wanted the to somehow use the h2 gas for something. how would you collect it?
@@timno9804 and I'd assume you filter it by putting the mixture in conditions that would cause the other components to react with something?
