Electrochemical equivalent, represented commonly by the symbol Z, is formally defined as the exact mass of a chemical substance that gets liberated, deposited, or dissolved at a specific electrode when an electric current of exactly one ampere is passed continuously through the electrolytic solution for a duration of exactly one second, or equivalently when one coulomb of electrical charge is successfully transferred through the system during the course of the electrolysis process.
