Abstract
The suitability of the oxazine dyes gallocyanine, solochrome prune AS, gallamine blue and celestine blue as indicators in the complexometric titration of bismuth (III), zinc (II), cadmium (II) and thallium (I) is examined and satisfactory conditions for their functioning are developed using EDTA and CyDTA as titrants. The colour changes at the equivalence point are very sharp and the results obtained are in agreement with those reported by other standard methods.
