Betteridge D: Extractive indicators in complex-formation titrations: theory and practice. Talanta. 1966 Nov;13(11):1497-516.
The use of conditional constants to predict the optimum conditions for titration in several complex-formation titrations, in which the end-point is detected by the formation of a coloured extractable complex, is demonstrated. The predictions have been tested by experiment. 2-(2-Pyridylazo)-1-naphthol is shown to be a useful extractive indicator for the copper-EDTA titration; dimethylglyoxine is not recommended as an extractive indicator for the nickel-EDTA titration; the titration of fluoride with aluminium, using 8-hydroxy-quinoline as an extractive indicator, is shown to be undesirable theoretically and experimentally. |
