Pharmaceutical and Medicinal:
The human body needs a certain amount of potassium, which is why potassium chloride is often prescribed to treat and prevent hypokalemia (low blood levels of potassium) or to help replenish electrolytes.
Potassium chloride is also used in some cardiac surgery procedures that cannot be carried out on the beating heart. Surgeons temporary story the heart by injecting it potassium chloride.
Potassium chloride can be used as a salt substitute in food, but if not added in measured proportions it can leave a metallic aftertaste.
Potassium chloride is also key ingredient in de-icing products. It has less of an impact on the environment and is safer for pets and plants.
Potassium chloride (KCl) is odorless and has a clear, almost colourless appearance. It is salty and easily dissolves in water. It is made up of small crystals that cleave in three directions and adopts a face-centered cubic structure. Potassium chloride is a metal halide salt that appears in nature as the mineral sylvite. It is composed of potassium and chlorine. It can be both extracted from nature and synthesized. Potassium chloride is often used in medicine, scientific applications, and food processing.
In 1807, Sir Humphry Davy was experimenting with a variety of compounds and discovered that potassium chloride can be extracted by applying an electrical current to molten potash. He also discovered that he could separate potassium from chloride by using alcohol. Later on, in the 1920’s, physicians began using it for medicinal purposes. It was even once used as a fire extinguishing agent.
