Salts from the sea – Sea-water is a mixture of various salts such as magnesium, potassium metals, calcium, and sodium.
In fact, sea-water contains about 3.6 percent by mass of dissolved salts which include the following salts
- Sodium chloride (Common salt) – 2.8 percent
- Magnesium salts – 0.6 percent
- Potassium salts – 0.1 percent
- Calcium salts – 0.1 percent
Thus, the most abundant salt present in the sea-water is sodium chloride (common salt).
Preparation of Common Salt from Sea-Water – Common salt is the most abundant salt is present in the sea-water. Therefore, sodium salt (common salt) is prepared commercially from sea-water. The common salt is prepared from sea-water as follows
Sea-water is collected in small lagoons (shallow lakes) on the shores of the sea in coastal areas. This sea-water is then allowed to evaporate by the heat of the sun. After that, all the sea-water is collected in the…
