Question

How might salt extract from seawater become common table salt?

Answer 1

we see in our daily life that if we mix sand in water and then keep the water in sunlight after a period of time the water will evaporate and sand will be left behind the almost the same concept is used here. Commercially available sea salts on the market today vary widely in their chemical composition. Although the principal component is common salt, the remaining portion can range from but 0.2 to 10% of other salts.

Complete step-by-step answer:
Our country is a major producer of sea salt. The necessary things which a person needs to make sea salt is a series of large pool or large containers which are progressively evaporated. Firstly we will take the sea salt which is also known as brine solution in the large pool and let the water evaporated in sunlight after the white substance is concentrated which is our salt. It is transferred to a small pool which then heated or placed in sunlight until no water is left. This salt is further collected, purified and packed to send to our home but the thing is we use iodized salt at our home which is good for our body and prevent our body from serious diseases also. So before coming to our home it is processed in factories to make it iodized and hence our table salt is prepared and ready to use.

Note: Salt is a mineral composed primarily of sodium chloride, a chemical compound belonging to the larger class of salts; salt in its natural form as a crystalline mineral is known as rock salt or halite. Salt is present in vast quantities in seawater, where it is the main mineral constituent.
