preparation of salt in ancient days and explain the process
Answers
Salt is the common name for the substance sodium chloride (NaCI), which occurs in the form of transparent cubic crystals. Although salt is most familiar as a food supplement, less than 5% of the salt produced in the United States is used for that purpose. About 70% is used in the chemical industry, mostly as a source of chlorine. Salt is also used for countless other purposes, such as removing snow and ice from roads, softening water, preserving food, and stabilizing soils for construction.
The earliest humans obtained their salt from natural salt concentrations, called licks, and from meat. Those people who lived near the ocean may have also obtained it by chewing seaweed or from the natural evaporation of small pools of seawater. Meat became a more important source of salt as hunting was developed, as did milk when sheep, goats, horses, camels, reindeer, and cattle were domesticated. Even today, certain peoples—such as the Inuit of the far north, the Bedouin of the Middle Eastern deserts, and the Masai of east Africa—use no other form of salt.
Explanation:
- Salt is the common name for the sodium chloride (NaCI) substance.
- Salt production is one of the oldest man-made chemical processes.
- Although when seawater evaporates, salt is generated naturally, the method can be readily reproduced to produce a greater output.
Procedure:
- Sea water includes a high quantity of common salt and dissolved salts from other metals.
- The sea water is gathered in shallow pits near the sea-shore and permitted to evaporate in sunlight.
- The water evaporates in a couple of days, leaving salt behind.
- The salt thus acquired is gathered and transferred to large plants where it is purified and packed for consumption.
