In 1807, Sir Humphrey Davy, an English chemist, discovered how to extract and isolate sodium from its compounds. Since sodium doesn't appear by itself in nature, this discovery lead to better understanding of sodium compounds, such as sodium chloride, which is the primary factor in the salinity of the oceans.
Sodium chloride, commonly known as salt, is an inorganic compound with many uses various industries and everyday life. Represented by the chemical formula NaCl, sodium chloride is best known as the primary ingredient in common table salt. It is also referred to as halite and is extracted from the oceans and from the Earth through mining..
