Zincon is a colorimetric indicator for Zn, Cu and Hg. Reagent for the spectrophotometric determination of zinc. Simultaneous determination of zinc and copper. Used in automated flow injection analysis of zinc. As a metal indicator for EDTA titration of Zn, or for the back titration of Ca in the presence of Mg with glycoletherdiaminetertraacetic acid (GEDTA or EGTA).
Reacts with Zn (pH 8,5 to 9,5) and Cu (pH 5,0 to 9,5) to form blue chelates. Also color reaction occurs with Co, Ni and some other polyvalent cations, Beer's law is observed in the range of 0,1 to 2,4 μg Cu/ml in water at 600 mu.
Slightly soluble in water and alcohol. Insoluble in most organic solvents. Soluble in aqueous alkali resulting in a red solution.
