金属离子酸的离解常数可推导为Ka=Kw·K_(MOH)及Ka_n=Kw·K_(M(OH)n)。在金属离子存在下滴定游离酸,可以作为混合酸进行理论处理,使用相同的滴定条件与等当点pH计算公式。在加入掩蔽剂滴定时,可以使用金属离子酸的条件稳定常数作出相似的理论处理。
The dissociation constants of metal ion acids can be deduced as Ka = Kw · K_ (MOH) and Ka_n = Kw · K_ (M (OH) n). Titration of the free acid in the presence of metal ions can be done theoretically as a mixed acid using the same titration conditions and equivalent pH calculation. A similar theoretical treatment can be performed using the conditional stability constants of the metal ion acids when adding the masking agent titration.
