According to Faraday’s first Law of electrolysis mass of substance liberated is equal to

Explanation

According to Faraday's First Law of Electrolysis, the mass (m) of a substance liberated or deposited at an electrode is directly proportional to the total charge (Q) passed through the electrolyte. This can also be expressed in terms of the substance's equivalent weight (e).

m=e⋅Q

Where:

• m = mass of the substance liberated (in grams),
• e = equivalent weight of the substance (g/C),
• Q = total charge passed (in coulombs).
