Question

How are Faraday’s laws of electrolysis helpful in exploring the quantitative aspect of electrolysis?

Answer 1

1. Faraday’s laws of electrolysis help in exploring the quantitative aspect of electrolysis by providing a direct relationship between the amount of substance deposited or liberated at an electrode and the quantity of electricity passed through the electrolyte.
2. According to Faraday’s first law, the mass of a substance deposited is directly proportional to the quantity of electricity passed, and according to the second law, when the same quantity of electricity is passed through different electrolytes, the masses of substances deposited are proportional to their chemical equivalents.
3. These laws allow the calculation of the exact amount of material deposited or gas evolved during electrolysis by using the current and time and are therefore very useful in practical applications like electroplating, refining of metals, and production of chemicals.
