【摘要】 用热力学中的晶格能、焓变、熵变及自由能的数据对离子化合物的溶解度和氢卤酸的酸性进行了分析.从熵变和焓变的角度解释了离子化合物的溶解度与离子电荷、离子半径、水化程度的关系,给出了判断溶解度大小的依据,解释了氢氟酸为什么最弱.更多还原

【Abstract】 With the data of crystal lattice, entropy change, enthalpy change and free energy in thermodynamics, this essay makes analysis on the solubility of hydronium compound and the acidity of hydrosulphuric acid. It explains the relationship between solubility of hydronium compound and hydronium charge, hydronium semidiameter and degree of hydratation. It gives basis on judging the degree of solubility and also explains why hydrofluric acid is the weakest.更多还原
