Vedclass · Answer

(C) Faraday's $2^{nd}$ law states that when the same quantity of electricity is passed through different electrolytes,the masses of different substances deposited at the respective electrodes are directly proportional to their equivalent masses.Equivalent mass is defined as $\frac{	ext{Atomic mass}}{	ext{Valency}}$.Therefore,the mass deposited $m \propto \frac{	ext{Atomic mass}}{	ext{Valency}}$.

Faraday's $2^{nd}$ law of electrolysis states that the mass of a substance deposited at an electrode is directly proportional to its:
