Question

Write Faraday's laws of electrolysis.

Answer 1

Faraday's first law states that the mass of a substance that is deposited or liberated at an electrode is directly proportional to the amount of charge passed.

$W=ZQ$ where W is the mass of the substances and Q is the charge and Z is the electrochemical equivalent.

The second law states that the mass of a substance deposited/liberated at an electrode on passing a specific amount of charge is directly proportional to its chemical equivalent weight.

If $W_1$ and $W_2$ are the mass of the substances and $E_1$ and $E_2$ are their equivalent weight than,

$\frac{W_1}{W_2}=\frac{E_1}{E_2}$
