一般說明
氯化钾属碱金属卤化物，为无色结晶盐。它在水中的溶解度与温度的升高成正比。它可以从氢氧化钾，通过中和反应与盐酸。已经描述了氯化钾在水中的溶液的焓的量热估计。
應用
可用于磷酸盐缓冲液制备，以及蛋白提取和溶解。
氯化钾可用于制备肥料、氢氧化钾、碳酸钾和其他钾盐。可用于缓冲液去质子化（质子 H + 损失）过程中焓和热容值的量热测定。根据这些值，计算这些缓冲液 pH 值的温度依赖性。

Many materials used in the medical settings such as catheters and contact lenses as well as most biological tissues are not purely elastic, but rather viscoelastic. While substrate elasticity has been investigated for its influence on bacterial adhesion, the impact

High-protein diets induce alterations in metabolism that may prevent diet-induced obesity. However, little is known as to whether different protein sources consumed at normal levels may affect diet-induced obesity and associated co-morbidities.
