Edta is short for ethylenediaminetetraacetic acid. A blue dye called eriochrome black t (eriot) is used as the indicator. This blue dye also forms a complex with the calcium and magnesium ions, changing colour from blue to pink in the process. The dye–metal ion complex is less stable than the edta–metal ion complex.
