Potassium Nitrate formula, also known as Saltpeter formula or Nitrate of potash formula is explained in this article. This alkali metal nitrate is an ionic salt of potassium ions and nitrate ions. It is a natural source of nitrate and is commonly used as a constituent in food preservatives, rocket propellants, fertilizers, fireworks, and tree stump removal. The chemical or molecular formula of Potassium Nitrate is KNO3.
It is a crystalline solid white to dirty grey in colour, which is odourless and has a cooling, saline pungent taste. it appears as a colourless gas and its fumes have a pungent irritating odour. It is colourless in its anhydrous form. In its natural form, it occurs as a mineral nitre. It is a strong oxidizer and is widely used in the production of in medicine, fertilizers, and making gunpowder.
