Question

State True or False.

The mass of a substance deposited on the cathode or anode during electrolysis is given by w = $\frac{Eit}{F}$

• A. True
• B. False

Answer 1

The correct option is A True

Faraday's first law of elecrolysis :

This law states that "The amount of a substance deposited or dissolved at an electrode is directly proportional to the charge passing through the electrolytes. If a current of I amperes is passed for t seconds, the quantity of charge Q in coulombs.

If W, gram of substances is deposited by Q coulombs of electricity, then

W = Zit = Eit/96500

Where Z is constant of proportionality and is known as electrochemical equivalent.
