The process is called the chlor-alkali process, wherein electricity is passed through an aqueous solution of sodium chloride (brine), resulting in the production of chlorine gas and sodium hydroxide.

The common salt obtained from the chlor-alkali process is sodium chloride (NaCl), which serves as a raw material for producing various everyday substances like sodium hydroxide and chlorine gas.
