电位滴定法是通过被测溶液电位(或pH)变化来确定终点的容量分析方法。选用合适的电极系统,可以进行氧化还原、沉淀、络合、中和及非水滴定终点的判断。特别对那些有颜色或浑浊的体系,以及在非水滴定时找不到合适指示剂的情况下尤为适用。 Potentiometric titration is a method of volumetric analysis that determines the endpoint by measuring the change in potential (or pH) of the solution. Selection of a suitable electrode system allows for the determination of redox, precipitate, complex, neutralization and non-aqueous titration endpoints. This is especially true for systems that are colored or cloudy, and where no suitable indicator can be found at non-drop timing.
