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

Options

A. one ampere per second.
B. 96500 coulombs per second.
C. one ampere for one hour.
D. charge on one mole of electrons.

Answer

D

Explanation

`underset(1 "mole")(A^(+)) + e^(-) to underset("1 mole")(A)`
`therefore` Charge of 1 mole electron is required for deposition of 1 equivalent of substance .
