| 摘 要： | 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，结果令人满意，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。

| Abstract: | 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. |

| Keywords: | Acid-base titration Least square methed Ion activity |
