| 摘 要： | 在估计出H ]的大致范围后,利用二分区间迭代法精确计算弱酸弱碱盐达到水解平衡时的pH值及其离子浓度,当最近两次迭代的正电荷总浓度与负电荷总浓度的相对偏差小于10-10时,即可认为正负和总浓度相等,即得结果;此方法还可用于计算缓冲溶液及有络合物生成的体系,也得到很好的结果.

| Abstract: | After rough estimate of H~ ], precise equilibrium concentration of various components formed by weak-acid-weak-base-salt has been calculated by halved-iteration when the positive ionic concentration is equal to negative ionic concentration, i.e., the relative deviation between positive ionic concentration and negative ionic concentration is less than 10~(-10). The method can also be used in the system containing buffer and coordination. |
