Sodium is a soft, silvery-white, highly reactive metal and chemical elements symbol Na and atomic number 11. Sodium is the most common alkali metal and the sixth most abundant element on Earth, comprising 2.8 percent of Earth's crust. It occurs abundantly in nature in compounds, especially common salt—sodium chloride (NaCl)—which forms the mineral halite and constitutes about 80 percent of the dissolved constituents of seawater. Sodium has many usefulcompounds like Sodium Acetate, Sodium Phosphate, Sodium Bicarbonate, Sodium Carbonate, Sodium Chloride, Sodium Thiosulphite, and Sodium Metabisulphite which can be used in different industries for production of multiple products.
