Description

(A) Electrochemical equivalent

(ii) Mass of substance deposited by one coulomb of charge

The mass of a substance that is deposited or evolved at an electrode during electrolysis when a unit quantity of electric charge (1 coulomb) passes through the electrolyte.

(B) Faraday

(iii) Charge carried by one mole of electrons

A unit of electric charge equal to the charge carried by one mole of electrons. It is named after Michael Faraday, who discovered electrolysis.

(C) Ampere

(iv) One coulomb of electric charge passed through one second

The unit of electric current. It is defined as the flow of one coulomb of charge per second.

(D) Electrical energy

(i) (\text{Potential difference } x \text{Quantity of charge})

The work done by electric charge. It is measured in joules.
