一般认为弱一元碱的ＣｂＫｂ大于１０－８时可直接用盐酸标准溶液滴定．在ＣｂＫｂ小于１０－８的情况下，根据在溶液中的电荷平衡推导出滴定消耗的酸标准溶液摩尔数与弱一元碱摩尔数之间的线性关系及分析误差△Ｖｅ／Ｖｅ小于１．０％的滴定终点范围，以此为依据提出标准曲线法测定强碱弱酸盐含量的方法．实验结果表明，ＣｂＫｂ大于１０－１２的条件下可以获得满意的结果．
Is generally considered weak monobasic CbKb greater than 10-8 can be titrated with hydrochloric acid standard solution. In the case of CbKb less than 10-8, based on the charge balance in solution, the linear relationship between the number of moles of acid standard solution consumed for titration and the number of moles of weak univalents and the analytical error △ Ve / Ve of less than 1.0% Titration endpoint range, based on which a standard curve method for the determination of strong alkali weak acid salt content method. The experimental results show that satisfactory results can be obtained when the CbKb is greater than 10-12.
