Potassium Chloride is commonly used as a laboratory reagent as a standard. It may be used as a calibration standard ionic solution for measuring electrical conductivity because KCl solutions, when prepared carefully, produce repeatable measurable properties. KCl is also a good source of ionic chloride, which should precipitate insoluble chloride salts upon addition to a solution of an appropriate metal ion. Commonly used in fertilizer.
Soluble in water (340 mg/ml at 20° C), alcohol (slightly), and ethanol (1 g/250 mL). Insoluble in ether, and acetone.
