Location And Processing
Sodium chloride, found abundantly in nature, occurs in seawater, other saline waters or brines, and in dry rock salt deposits. It can be obtained by mining and evaporating water from brines and seawater. This salt can also be prepared chemically by reacting hydrochloric acid (chemical formula HCl) with sodium hydroxide (chemical formula NaOH) to form sodium chloride and water. Countries leading in the production of salt include the United States, China, Mexico and Canada.
