本文从决定多元弱酸滴定曲线突跃的因素出发,并依据视觉误差和终点误差的要求,从新推出多元弱酸分步准确滴定的条件,并讨论了分布准确滴定条件的几何意义。
In this paper, starting from the factors which determine the sudden jump of multivariable weak acid titration curve and according to the requirements of visual error and end point error, the condition of stepwise accurate titration of multivariable weak acid is introduced. The geometric meanings of accurate titration conditions are also discussed.
