Potassium Chloride is a metal halide composed of potassium and chloride. Potassium maintains intracellular tonicity, is required for nerve conduction, cardiac, skeletal and smooth muscle contraction, production of energy, the synthesis of nucleic acids, maintenance of blood pressure and normal renal function. This agent has potential antihypertensive effects and when taken as a nutritional supplement may prevent hypokalemia.
Potassium chloride appears as white colorless cubic crystals. Strong saline taste. (NTP, 1992)
Potassium chloride is a metal chloride salt with a K(+) counterion. It has a role as a fertilizer. It is a potassium salt and an inorganic chloride.

2)Mainly used in the inorganic industry, it is the basic raw material for the manufacture of various potassium salts such as potassium hydroxide, potassium sulfate, potassium nitrate, potassium chlorate, and red strontium potassium.
3)The dye industry is used to produce reactive dyes and the like.
4)In agriculture, it is a potash. Its fertilizer efficiency is fast, it is directly applied to the farmland, which can raise the water in the lower layer of the soil and have the effect of drought resistance.
