A examination of the EDTA titration of manganese(II) taking into consideration formation of 1:1 and 1:2 complexes with Eriochrome Black T indicator.
In the EDTA titration of manganese(II) with Eriochrome Black T as indicator, the effect of formation of 1:1 and 1:2 manganese(II)-indicator complexes must be taken into consideration. The titration error can be reduced to less than 0.1%. For comparison purpose the titration of zinc(II) has also been studied.
