Question

What is the first law of electrolysis according to which the electrolytic processes take place?

(a) Ohm’ s law

(b) Henry’s law

(c) Faraday’s law

(d) Einstein’s equation

I got this question in an interview for internship.

I'm obligated to ask this question of Electrochemical Reduction Methods topic in portion Preparative Methods of Solid State Chemistry

Answer 1

Correct choice is (c) Faraday’s law

The best explanation: The first law of electrolysis is given by Faraday’s first law which states that the quantity of the element separated by electric current through a molten or dissolved salt is directly proportional to the quantity of the electric charge passed through the circuit. The equation for this law is given by m=eQ, where e=electrochemical equivalent and Q=charge.
