Potassium chloride

Potassium chloride KCl, or potassium salt is the metal halide salt composed of potassium in addition to chlorine. this is the odorless as well as has a white or colorless vitreous crystal appearance. The solid dissolves readily in water, and its solutions pretend a salt-like taste. Potassium chloride can be obtained from ancient dried lake deposits. KCl is used as a fertilizer, in medicine, in scientific applications, and in food processing, where it may be so-called as E number additive E508.

It occurs naturally as the mineral sylvite, and in combination with sodium chloride as sylvinite.

Chemical properties

KCl is soluble in a brand of polar solvents.

Solutions of KCl are common standards, for example for calibration of the electrical conductivity of ionic solutions, since KCl solutions are stable, allowing for reproducible measurements. In aqueous solution, it is for essentially fully ionized into solvated K^{+ and Cl– ions.}

Although potassium is more Le Chatelier's principle:

This method is the leading method for producing metallic potassium. Electrolysis used for sodium fails because of the high solubility of potassium in molten KCl.
