本文讨论了络合返滴定中,当返滴定的金属离子络合物比被测金属离子络合物更稳定时,返滴定的滴定曲线及滴定的可能性。举例说明了在这种情况下的滴定误差大小,并推导了滴定误差的计算公式。
This article discusses the possibility of back titration titration and titration of the backtitration titration in a complex back titration when the back titration of the metal ion complex is more stable than the measured metal ion complex. An example is given to illustrate the titration error in this case and to derive the formula for the titration error.
