Chemical compound
Potassium nitrate is a chemical compound with a sharp, salty, bitter taste and the chemical formula KNO 3. It is an ionic salt of potassium ions K+ and nitrate ions NO3−, and is therefore an alkali metal nitrate. It occurs in nature as a mineral, niter (or nitre outside the US).[5] It is a source of nitrogen, and nitrogen was named after niter. Potassium nitrate is one of several nitrogen-containing compounds collectively referred to as saltpeter (or saltpetre outside the US).[5]
Major uses of potassium nitrate are in fertilizers, tree stump removal, rocket propellants and fireworks. It is one of the major constituents of gunpowder (black powder).[6] In processed meats, potassium nitrate reacts with hemoglobin and myoglobin generating a red color.[7]
