| 摘 要： | 论述了ks在酸碱平衡中的重要作用。具体讨论了ks与 Ka、Kb的关系；ks决定了酸碱滴定反应完全度，为实现混合酸碱的连续滴定和极弱酸碱的滴定寻找出区分效应范围较大的非水溶剂；将kw与〔H＋〕、〔OH－〕关系引入PB E 中，导出酸碱水溶液〔H＋〕、酸碱滴定曲线方程、终点误差和缓冲容量计算式。提出了溶剂的pks只决定溶剂对酸碱的区分和拉平范围，但不决定溶剂的酸碱性的观点。

| Abstract: | The article discussed the improtance of Ks in the acid-base balance.The article discussed the relationship between Ks and Ka 、K b in detail;Ks decided the complete level of acid-base titration.In order to ac hieve mixing acid-base continous titration and the weakest acid-base titration , the paper studied the non-aqueous solvent that has wider range of differntiatin g effect.The connection of Kw And 〔H＋〕、〔OH 〕 was put in to PBE and then the formule 〔H+〕and equilibrium of acid-base titration curve and end-point error and buffer capacity were obtained in the acid-base solution.T h e article also mentioned the idea that pKs of solvent did not decide the propert y acid-base of acid-base but the range of differentiate effect and leveling ef fect to acid-base. |
