Question

The electric charge for electrode deposition of one gram equivalent of a substance is 

(a) one ampere per second 

(b) 96,500 coulombs per second 

(c) one ampere for one hour

(d) charge on one mole of electrons

Answer 1

The correct option (d) charge on one mole of electrons

Explanation:

Charge on one mole of electrons (6.023 x 10²³ electrons) is equal to one Faraday, so one gram equivalent of a substance will be deposited by one mole of electrons.
