Answer 2

Answer:

Common salt is sodium chloride, NaCl. It can be made in a laboratory by the reaction of sodium with chlorine. However, it is found naturally in large amounts in sea water or in underground deposits. It is often obtained either by evaporating sea water or by mining underground deposits.

The procedure is based on the electrolysis of molten sodium chloride (NaCl), table salt. Electrolyzing molten sodium chloride produces chlorine gas at the anode and sodium metal at the cathode. The commercial electrolytic process is called the Downs process.
