Question

explain the process use to obtain common salt fromsea water

Answer 1

Dear user !!

Evaporation is the basic process to obtain salt from sea water.

In this process, sea water is filled in craters made nearby sea area and 

allowed to remain under sunshine for long time {for some days indeed}.

The water gets evaporated and the salt remains behind which is further 

collected and purified more precisely.


Hope it helps you !!
