Class 12- Electrochemistry ( How to find product of electrolysis)// Preferential discharge of ion

The products of electrolysis depend on the nature of the electrolyte being electrolysed, and the type of electrodes used.

Inert electrodes do not participate in the chemical reaction.

Platinum, gold or graphite electrodes are commonly used as inert electrodes.

The electrolytic decomposition of aqueous sodium chloride solution produces sodium hydroxide, chlorine gas and hydrogen gas.

Process:

At the cathode, either sodium ions or hydrogen ions may be reduced. As the hydrogen ion has a higher standard electrode potential than sodium, it gets reduced. The hydrogen ions are produced by the dissociation of water.

Halide ions will undergo oxidation to form the diatomic elements in preference to water.

Chloride ions undergo oxidation in preference to water due to overvoltage of oxygen.

Thnks for such a lovely explanation.It helped me a lot💗

Sir ya apna oH negative ko is tarah kaise likha ya bata digia

[ektasaxena]

Sir in aq Nacl with Pt electrode why OH negative does reaction in anode and not CL negative

[rohitbaljot]

Anode -ve hota and Catholde +ve in case of electrochemistry when we talk about cell, anode is source of e- so oxidation take place there and cathode is source of +ve charge so redn take place there

[jayantideshpande]

Sir I have a doubt....
Sir electrons are negatively charged so why it is said that they are moving from anode to cathode.. I have seen in many videos in that it is said that electrons are moving from anode to cathode....
But sir how it is possible...
Two similar charges always repel so sir which is correct and what is the reason behind it????

[the_vanshika]

sir thank you so much 🙏
meri Sari problems ab clear ho rhi h

[shachisharma]

SIR I HAVE A BIGGEST DOUBT PLZ CLEAR
What is the SRP Of OH- ion? And, what will be the oxidation reaction of OH-?
Plz clear!!!

[PardeepKumar-slvj]

Sir have a doubt for the case of AgNO3 aq soln ag lies below hydrogen in series but since silver is deposited
