ON THE COMPLEXING ABILITY OF ERIOCHROME BLACK T AS A METALLOCHROMIC INDICATOR FOR SOME ALKALI AND ALKALINE EARTH CATIONS IN ACETONE AND DIMETHYLSULPHOXIDE SOLUTIONS
The interaction between eriochrome black T and Li , Na , K ,Mg and Ca ions in acetone and dimethylsulphoxide solutions has been investigated spectrophotometrically. The formation constants of the resulting 1 : 1 complexes were determined and found to decrease in the order Mg >Ca >Li >K &...
