Question

The electric charge for electrode deposition of 1 g equivalent of a substance is:

• A. 1 ampere per second.
• B. 96,500 coulomb per second.
• C. 1 ampere for 1 hour.
• D. charge on 1 mole of electrons.

Answer 1

The correct option is D charge on 1 mole of electrons.

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

1 g equivalent of a substance means one equivalent of substance which have total charge of one mole of electron.
