Solution
The electrochemical equivalent is the amount of substance which gets deposited from its solution on passing electrical charge equal to 1 coulomb.
Explanation:
Electrochemical equivalent (ECE) is defined as the mass of a substance deposited or liberated by the passage of 1 coulomb of charge during electrolysis.
It is related to Faraday’s first law:
Mass = ECE × Charge
∴ So, ECE is the amount deposited by 1 coulomb of electricity.
