【摘要】 利用热力学计算软件HSC Chemistry动态探究了二元弱酸酸式盐溶液的稀释过程，通过图示法研究了NaHCO₃,NaHS,NaHSO₃,NaHC₂O₄等2类典型的二元弱酸酸式盐溶液浓度与各微粒浓度之间的关系及变化规律，方便快捷地比较了不同浓度范围内溶液中各微粒浓度大小的排序，有利于厘清二元弱酸酸式盐溶液的电离平衡过程。更多还原

【Abstract】 The dilution process of dibasic weak acid salt solution was explored dynamically by thermodynamic software of HSC Chemistry. The relationships among particle concentrations and salt concentrations of two typical kinds of dibasic weak acid salt solution including NaHCO₃, NaHS, NaHSO₃ and NaHC₂O₄ were studied by graphical method. The order of particle concentrations in solutions with different concentration ranges was compared conveniently and quickly, which was helpful to clarify the ionization equilibrium process of dibasic weak acid salt solution.更多还原
