弱碱与微量强碱混合液的测定

Determination of a Weak Base and Trace of a Strong Base in a Solution

提出了强酸滴定弱碱与微量强碱共存的滴定通式，并提出用最小二乘法处理电位滴定数据，求算弱碱与微量强碱的浓度。结果今人满意。文中还解释了强碱的“空白”值是由于未进行活度校正引起的，而且经活度系数校正以后可获得更为准确的结果。

This paper presen ts a gercral equation of a strong acid to titrate a solution containing a weak base and trace of a strong base,The least square methed was used for calculating the concentrations of the two bases.The ' blank yalue' of strong base appeared because the ion activity coefficient was not calibrated.Thus the more accurate results can be obtained after calibration of the ion activity coefficient.
