Sodium Sulphate is a material whose chemical name is NaNO. This alkali metal nitrate salt is frequently referred to be Chile saltpeter in order to distinguish it from the common saltpeter, potassium nitrate. The mineral form is also known as nitrate, soda niter, and nitrate. Sodium nitrate is a white, liquefiable solid with a high water solubility. It is an easy way to obtain the nitrate anion (NO3), which is essential for several large-scale reactions that result in fertilizers, pyrotechnics, smoke bombs, and other explosives, glass, pottery enamels, food preservatives, and solid rocket propellant. Significant amounts of Sodium Sulphate have been mined for a variety of purposes.
