Product Application of Potassium chlorideCAS#7447-40-7

Potassium chloride (KCl) is used in drug preparations and as a food additive and chemical reagent. It is possible to reduce the sodium in your diet by substituting potassium chloride for table salt (sodium chloride), which may be healthier. Molten potassium chloride is also used in the electrolytic production of metallic potassium. KCl is also found in seawater brine and can be extracted from the mineral carnallite.
