Question

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

Easy

A

one ampere per second
B

96500 coulombs per second
C

one ampere for one hour
D

charge on one mole of electrons

Solution

$\underset{1 mole}{A^{+}} + e^{-} ⟶ \underset{1 mole}{A}$
$∴$ 1 mole electron of (1 F) is required for deposition of 1 equivalent of substance.
