Study on Reagent Volume in Reverse-Titrimetric-Analysis During Coordinate Chemical Reaction

利用Excel软件分析其金属离子在不同浓度下的终点滴定误差与过量EDTA的曲线关系 。

The curve-line relation between the finishing-point error with different concentration condition and excessive volume of EDTA was analysed with the help of Excel Software in checking metal ions by reverse-titrimetric-analysis during coordinate chemical reaction. Based on that relation, the maximum concentration of measured ions and its corresponding maximum excessive volume of EDTA with the condition of certain permitted finshing-point error were determined.
