could u plz explain about salts and their formation? plz giv an ans now.It'z urgnt

The common salt  is an important raw material for the production of sodium hydroxide, baking soda, washing soda and bleaching powder etc.

1.Sodium hydroxide(NaOH)

When electricity is passed through an aqueous solution of sodium chloride (called brine), it decomposes to form sodium hydroxide. The process is called the chlor-alkali process because of the products formed– chlor for chlorine and alkali for sodium hydroxide.

Bleaching powder

 chlorine is produced during the electrolysis of aqueous sodium chloride (brine).

This chlorine gas is used for the manufacture of bleaching powder.

Bleaching powder is produced by the action of chlorine on dry slaked lime [Ca(OH)₂]. 

Baking soda  -Sodium hydrogencarbonate (NaHCO₃).

It is produced using sodium chloride as one of the raw materials.

Washing soda - Na₂CO₃.10H₂O .
