This chemistry video tutorial provides a basic introduction into the electrolysis of water which splits H2O into H2 (hydrogen has) and O2 (oxygen gas). Oxygen gas is produced at the anode and hydrogen gas is produced at the cathode. Electrons flow from the anode to the cathode. Oxidation always occurs at the anode and reduction occurs at the cathode.

@user-ip8sj2xm4v 2 года назад

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.

@manitverma4425 Год назад

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

@safiulfaiyaz7038 2 года назад

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?

@aishaaziz9248 5 лет назад

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

I know this is old but when you give away, or gain electrons, it is an oxidation/reduction reaction. In the video example, Hydroxide is oxidized because it gives away 4 electrons.

We need to separate hydrogen from oxygen in the air Heatwaves are partially from vapour build up in the air

@wayneyadams Год назад

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

I am not sure about the reaction at cathode, Shouldn't it be 4 H2O + 4e- → 2H2 + 4OH- ?

@gergokovacs3332 3 года назад

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.
