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.
