What is a Potassium nitrate (KNO₃)?

Potassium nitrate (KNO₃) is an inorganic compound made from potassium and nitric acid. It is commonly known as saltpeter and appears as a white or colorless crystalline or granular solid, highly soluble in water. Potassium nitrate has a wide range of uses, especially in fertilizers, food preservation, and the production of explosives. In agriculture, potassium nitrate is used as a key source of nitrogen and potassium in fertilizers. Nitrogen is essential for plant growth, while potassium helps with water regulation and disease resistance. Thus, potassium nitrate increases crop yields and plays an important role in agricultural production.

Potassium nitrate is also used in explosives manufacturing, such as gunpowder, dynamite, and mining explosives, due to its strong oxidizing properties. In the food industry, potassium nitrate serves as a preservative to prevent spoilage in meat and fish. It plays an important role in maintaining the freshness of food. Due to its strong oxidizing nature, potassium nitrate requires careful handling. It should be stored properly to avoid exposure to heat or shock.
