Name the source from where sodium chloride is obtained
Mostly all the chemical compounds which consist of chlorine or sodium is usually derived from salts. It is distributed abundantly in nature. Salt is a major ingredient of the dissolved materials in seawater.
Pure salt can be obtained from mineral halite. Sodium chloride is obtained by mining the deposits and brine solution is obtained by passing water into the deposits. Hence the salts get dissolved then the solution is pumped out.
Evaporation of the sea water is one of the major processes used to obtain salt and is most widely followed in countries like India. The crystals obtained usually consists of impurities such as calcium sulfate, sodium sulfate etc. Pure crystals are obtained by dissolving the salts with little water and filtering the solution.
