Potassium

Description:

Potassium is an alkali metal. Potassium ions are an essential component of plant nutrition and are found in most soil types. They are used as a fertilizer in agriculture, horticulture, and hydroponic culture in the form of chloride, sulfate, or nitrate. The potassium cation is a nutrient necessary for human life and health. Potassium chloride is used as a substitute for table salt by those seeking to reduce sodium intake so as to control hypertension. Vapor of pure potassium is used in several types of magnetometers. It can also be used in reactive distillation.
