The chemical compound potassium chloride is a metal halide salt composed of potassium and chlorine. White potash, sometimes referred to as soluble potash, is usually higher in analysis and is used primarily for making liquid starter fertilizers. Potassium chloride is used in medicine, scientific applications, food processing and in judicial execution through lethal injection. It occurs naturally as the mineral sylvite and in combination with sodium chloride as sylvinite. It is sometimes used in water as a completion fluid in petroleum and natural gas operations, as well as being an alternative to sodium chloride in household water softener units. Along with sodium chloride and lithium chloride, potassium chloride is used as a flux for the gas welding of aluminium.
