许多固体物质在水溶液里的饱和溶解度随温度的升高而增大,一些教材上认为达是由于这些溶解反应是吸热过程,因而温度升高,饱和溶解度增大。这种解释显然是以Le Chatelier原理或热力学公式
The saturation solubility of many solid materials in aqueous solution increases with the increase of temperature. Some materials suggest that these dissolution reactions are endothermic and therefore the temperature rises and the saturated solubility increases. This interpretation is obviously based on Le Chatelier’s principle or thermodynamic formula
