络合滴定中分别滴定判别式的使用

The use of stepwise titration discriminant in complexometric titration

讨论了络合滴定中分别滴定判别式lgcspMK'MY≥5,lgcspMK'MY=Δlg(cK)≥5和lgcspMK'MY=Δlg(cK')≥5的判别方法.通过对Δlg(cK')≥5的推导,阐明K'的计算方法.

Stepwise titration dlscnmmant lgC^SP_M K′_MY≥5,lgC^SP_M K′_MY=△lg（cK）≥5 and lgC^SP_M K′_MY=△lg（cK′）≥5 were discussed. The calculation of K＇ was illustrated by deducing △lg（cK′）≥5.
