Salt, also known as sodium chloride, is a chemical compound that is an essential element in the diet of humans, animals, and even many plants. Since prehistoric times, salt has been used to preserve foods and was commonly used in the religious rites of the Greeks, Romans, Hebrews, and Christians. Salt, in the form of salt cakes, served as money in ancient Ethiopia and Tibet. As long ago as 1450 BC, Egyptian art shows records of salt production.

The simplest method of obtaining salt is through the evaporation of salt water from areas near oceans or seas. In most regions, rock salt is obtained from underground mining or by wells sunk into deposits. Salt is soluble in water, is slightly soluble in alcohol, but is insoluble in concentrated hydrochloric acid. In its crystalline form, salt is transparent and colorless, shining with an ice-like luster.
