Beschreibung

Allgemeine Beschreibung

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. Calorimetric estimation of the enthalpy of solution of potassium chloride in water has been described.

Anwendung

Potassium chloride may be used in the preparation of fertilizer, potassium hydroxide, potassium carbonate and other potassium slats. 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.
Potassium chloride can be used as a fertilizer and as a regenerant to soften water. It has been used a buffer for the separation of major purine metabolites in the heart, using reverse phase ion pair chromatography(RPIPC).

Kann für die Herstellung von PBS-Puffern und für die Extraktion und Solubilisierung von Proteinen benutzt werden.
