热力学原理是讨论物质溶解度的有效方法之一 .运用热力学原理对一定条件下卤化银在水中的溶解度变化规律进行了解释 ,分析了引起卤化银在水中溶解度发生变化的各种因素 ,说明使卤化银在水中的溶解度由氟化银到碘化银依次减小的最主要因素不是离子极化 ,而是卤素离子水化能 .
The principle of thermodynamics is one of the effective methods to discuss the solubility of matter.Using the principle of thermodynamics to explain the variation of solubility of silver halide in water under certain conditions, the factors that cause the change of solubility of silver halide in water are analyzed, Solubility in water from silver fluoride to silver iodide in order to reduce the most important factor is not ion polarization, but halide ion hydration energy.
