Electrolysis is the chemical decomposition produced by passing an electric current through a liquid or a conducting solution.
Its applications are as follows:

● Electroplating: In electroplating, the layer of one metal is deposited on other metal to prevent it from corrosion.

● Electrorefining: It is used for extracting impurities from crude metals.

● Electrometallurgy: It is the process of extraction of metals from their respective ores by electrolysis.
