General description
Potassium chloride, an alkali metal halide, is a colorless crystalline salt. Its solubility in water is directly proportional to increase in temperature. It can be prepared from potassium hydroxide, via neutralization reaction with HCl.[1] Calorimetric estimation of the enthalpy of solution of potassium chloride in water has been described.[2]
Application
Potassium chloride may be used in the preparation of fertilizer, potassium hydroxide, potassium carbonate and other potassium slats.[1] It may be used in the calorimetric determination of enthalpy and heat capacity values during the deprotonation (loss of proton H+) of buffers. From these values temperature dependence of the pH of these buffers was calculated.[3]
Potassium chloride can be used as a fertilizer and as a regenerant to soften water.[4] It has been used a buffer for the separation of major purine metabolites in the heart, using reverse phase ion pair chromatography(RPIPC).[5]

May be used for the preparation of phosphate buffered saline, and for the extraction and solubilization of proteins.
