Describe the Process of Electrolysis in the Production of ...

Electrolysis is the process of using electric current to induce a chemical reaction. The chemical reaction in question is typically a reduction-oxidation reaction, wherein atoms exchange electrons and change oxidation states. This process can be used to produce metal solids, which is useful for electroplating and the purification of various metals.
