evaporation
Early humans removed salt from seawater primarily through evaporation. They would collect seawater in shallow pools or containers and allow the sun and wind to evaporate the water, leaving salt crystals behind. This method, known as solar evaporation, was simple and effective, enabling them to harvest salt for culinary and preservation purposes.
desalinationSaline comes from the Latin word salinus which means salty.
Early humans removed salt from seawater primarily through a process known as evaporation. They would collect seawater in shallow pools and allow the sun to heat the water, causing it to evaporate and leaving behind salt crystals. This method was simple and utilized natural elements, making it effective for obtaining salt for various uses.
Yes, salt water can be separated by evaporation. When the salt water is heated, the water evaporates, leaving the salt behind. The vapor can then be collected and condensed back into liquid water, leaving the salt separated.

Salt is not evaporated.
Actually, saltwater is a mixture since the water and salt can be removed by evaporation.
It can be filtered out or removed by evaporation/ destillation.

Normally the salt is removed from the water by the process of evaporation, using the sun's rays to remove the water.
Physical Change
- by the evaporation of water crystallized sodium chloride is obtained - by distillation of water sodium chloride is obtained as a residual product
The evaporation of water is slow when water is dissolved in salt. This is because of the salt molecules, the salt molecules is the reason for the slow evaporation.
Salt is obtained after the evaporation of water.
