Common Salt [Sodium Chloride (NaCl)]
Common salt is formed by the combination of hydrochloric acid and sodium hydroxide solution. It is the salt that we use in food. Sea water contains many salts dissolved in it. It is obtained on large scale from sea water by separating other salts from it. It may also be obtained from rock salt.
Deposits of solid salt are also found in several parts of the world. These large crystals are often brown due to impurities. This is called rock salt. Beds of rock salt were formed when seas of bygone ages dried up. Rock salt is mined like coal.
Common salt is an important raw material for various materials of daily use, like sodium hydroxide, baking soda, washing soda, bleaching powder etc.
