Potassium salts are chemical compounds that contain potassium ions (K+) combined with various anions, such as chloride, sulfate, or nitrate. They are commonly found in nature and are essential for many biological processes. Potassium salts are often used in fertilizers to promote plant growth, as potassium is a vital nutrient for crops. In addition to agriculture, potassium salts have various industrial applications. They are used in food preservation, as well as in the production of soaps and detergents. Some potassium salts, like potassium chloride, are also used as a salt substitute for those looking to reduce sodium intake.
