• 9650 coulombs

• 965 coulombs

• 1 coulomb

Answer 1

Electrochemical equivalent (z) is the amount of substance which gets deposited from its solutions on passing electrical charge equal to solutions 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.
