Question

Which method is used to obtain common salt from sea water? Why?​

Answer 1

Answer:

Salt is obtained from seawater by the process of Evaporation.

Explanation

Seawater is trapped in large, shallow pools and allowed to stand there. The sun’s heat evaporates the water slowly, and common salt is left behind. This salt is further collected, purified and packed for domestic use. The concentrated brine precipitates the salt, which is then gathered by mechanical harvesting machines. Any impurities that may be present in the brine are drained off and discarded before harvesting.

 It is used as a seasoning in foods, cooking, cosmetics and for preserving food.

Sea salt and table salt contain comparable amounts of sodium by weight.

Answer 2

Answer:

The Correct Answer is Evapouration

Explanation:

Seawater is captured and allowed to stand in enormous, shallow pools. The sun's heat eventually evaporates the water, leaving ordinary salt behind. This salt is then gathered, cleaned, and packaged for usage in the home. The salt is precipitated by the concentrated brine, which is subsequently collected by mechanical harvesting equipment. Before harvesting, any pollutants that may be present in the brine are drained and eliminated.

It's used as a flavouring, in cooking, in cosmetics, and in food preservation.

Table salt and sea salt both have about the same amount of sodium by weight.
