摘要
本文用严格的数学方法从理论上系统探讨了弱酸混合酸的分步滴定问题和总酸量的滴定问题,提出了在允许误差ε=0.2％、突跃范围ΔpH=0.6条件下的混合酸准确滴定判据。
An approach based on mathematics is used to study the titration of mixed acid of weak acids with strong base.The accuracy of the titration of mixed acid of weak acids is studied theoretically,and a criterion is put forward which can be used to judge whether the mixed acid given can betitrated accurately.
