本文测定了KCl,KBr、KNO_3、NaCl、CsCl、NH_4Cl六个盐在甲醇-甲苯、苯、萘、四氯化碳、环己烷及1,4二氧六环,六种混合溶剂中的溶解度,得经验公式kig_S_m~S_λ=kx_(Ne),关于离子在混合溶剂中的溶剂(甲醇)化条件,文中作了某些假设,并在Cox等人工作的基础上,对这个体系进一步推导出电解质的迁移自由能.同时结合迁移自由能与溶解度的热力学关系,推导得电解质溶剂化数公式n_++n_-=-2 ln S_0/S_m/ln φ_0. 文中最后计算得各个盐的甲醇化数为:KCl=7.3,NaCl=6.4,NH_4C_1=5.3,KBr=6.6,CsCl=6.3,KNO_3≈7.4.
The solubility of six salts of KCl, KBr, KNO_3, NaCl, CsCl and NH_4Cl in methanol, toluene, benzene, naphthalene, carbon tetrachloride, cyclohexane and 1,4-dioxane , The empirical formula kig_S_m ~ S_λ = kx_ (Ne), some assumptions about the solvent (methanol) conditions of the ions in the mixed solvent, and based on the work of Cox et al., This system is further deduced The free energy of migration of the electrolyte was calculated.At the same time, based on the thermodynamic relationship between the free energy of migration and solubility, the solvation formula of electrolyte was deduced: n _ ++ n _ - = - 2 ln S_0 / S_m / ln φ_0. As follows: KCl = 7.3, NaCl = 6.4, NH_4C_1 = 5.3, KBr = 6.6, CsCl = 6.3, KNO_3≈7.4.
