What is an Electrolytic Cell ?

A device in which electrical energy is converted into chemical energy or chemical energy is converted into electric energy is called an Electrolytic cell

The electrolytic cell consists of two metallic electrodes and an electrolyte.

In this cell nomenclature, the electrode to the left of the salt bridge is always assumed to be the anode, and the accompanying half-equation is always stated as an oxidation , while right side is cathode and the half equation is Reduction.

Reaction at Anode: Au(s) → Au³⁺(aq) + 3e⁻  ..........(oxidation)

Reaction at Cathode: Au³⁺(aq) + 3e⁻ →Au(s) ..............(reduction)
