摘要
金属卤化物水溶性规律一直是困扰大一新生的问题。本文从原子结构和分子结构出发归纳了金属卤化物的化学键,再根据化学键的强弱分析其水溶方式,同时配以热力学数据讨论了其溶解过程中的能量变化,最后归纳出了金属卤化物的水溶性规律。
The first-year undergraduates are always racked by the solubility rule of metal halides in water. In this paper,firstly,the chemical bonds were deduced from atomic structures and molecular structures. Then,the dissolve modes in water were derived from the chemical bonds. Thirdly,the correlation between the energy changes and the solubilities was analyzed based on thermodynamic data,and finally,the solubility rule of halides in water was revealed.
