Question

What is electrochemical equivalence and equivalent weight?

Answer 1

Electrochemical equivalent of a substance may be defined as the mass of the substance deposited when a current of 1 Ampere is passed for 1 Second, i.e. a quantity of electricity of one Coulomb is passed

Equivalent weight is the mass of a substance especially in grams that combines with or is chemically equivalent to eight grams of oxygen or one gram of hydrogen. We can find the equivalent weight of a substance by dividing the molar mass by valency.
