Potassium chloride is a strong electrolyte, soluble in water and alcohol. Potassium chloride has many uses as a fertilizer, food additive, water softener and desiccant.
It is also used in the manufacture of glass, pottery, porcelain enamel and cement. It is used to produce potassium hydroxide (KOH) by reacting with sodium hydroxide at high temperature.
Potassium chloride is obtained by evaporating brine solution containing up to 60% KCl content from underground deposits. It can also be obtained from seawater by separation of its ions by fractional crystallization or ion exchange techniques.
