无机盐在水中的溶解度可表示为Pkm=-lgS,S为重量摩尔浓度表示的溶解度。影响无机盐溶解度的主要因素是晶体的晶格能和组分离子的水合能以及溶解过程中的熵效应等。根据无机盐的溶解度与其组分离子的半径r、电荷Z的关系来分析,晶格能、水合能均与离子的极化作用有关。由于极化理论是离子键理论的重要补充,极化的结果可使键型发生改变,因
The solubility of inorganic salts in water can be expressed as Pkm = -lgS, and S is the solubility expressed in terms of molarity. The main factors affecting the solubility of inorganic salts are the crystal lattice energy and the hydration energy of the component ions and the entropy effect in the dissolution process. According to the solubility of inorganic salts and the radius of its component ions r, the charge Z analysis, the lattice energy, hydration energy and ion polarization are related. Since polarization theory is an important complement to the ionic bond theory, the result of polarization can change the type of bond due to
