Saltpeter, also known as Potassium nitrate (KNO3) is a white crystalline solid that is commonly found as a powder. The majority of saltpeter (potassium nitrate) is created by a chemical reaction between nitric acid and potassium salts. It’s simple to produce it in the lab by reacting ammonium nitrate and potassium chloride in water.
KNO3 is used as a form of fertilizer as it contains all the macronutrients needed for the plants to grow.
