摘要:

对分析化学中的四种容量分析方法进行了归纳和比较,从滴定的可行性、终点误差的计算公式、指示剂的作用原理、突跃范围及影响因素等方面比较其异同点,推导了各种滴定方法突跃范围的计算公式。

关键词: 容量分析, 滴定可行性, 终点误差, 突跃范围

Abstract:

The four volumetric analyses were summarized and compared in the feasibility of titration, the formula of end point error, the allochroic principle of indicators, and the influencing factors for jump ranges. The computational formula for jump ranges were deduced.

Key words: Volumetric analysis, Feasibility of titration, End point error, Jump range
