对混合离子分步滴定最佳酸度的讨论

Optimum Acidity of Step Titration M ixed Ion

用配位滴定法对混合离子进行分步滴定时,将pH_(?)定为最佳酸度范围的低限是否合理。在最佳酸度范围内有一最佳pH值能否作为一普遍规律的结论,文章从三种不同类型的实例,论证上述结论的局限性。

With three different sorts of examples, the Limitation of the conclusion has been proved that whether it is rational to minimum limit optimim acidity when to step titrate mixed ion with the coodinatcd titration, that whether it can be considered as a general law that there is a optimum PH value in optimum acidity.
