詳細

詳細

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.

アプリケーション

Potassium chloride may be used in the preparation of fertilizer, potassium hydroxide, potassium carbonate and other potassium salts. 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.

リン酸緩衝生理食塩水の調製及びタンパク質の抽出や可溶化に用いられます。
