Question

relation between electrochemical equivalent and equivalent weight proof

Answer 1

Dear Student,

Equivalent weight of a solution is the molecular weight of the solute divided by the valency of the solute(n-factor). Equivalent weight predicts the mass of a substance that will react with one atom of hydrogen in an acid-base analysis.

$EquivalentWeight=\frac{Molecularweight}{n-factor}$
Electrochemical equivalent or ECE of an element is the mass of that element liberated or deposited at an electrode when one coulomb of electricity is passed through an electrolytic cell.

$W=zIt$

where W is mass of element liberated or deposited, I is the current passed and t is time for which current passed and z is called as electrochemical equivalent or ECE.

Note: These two are different things, not related to each other.
