WebComplexometric titrations with EDTA have been reported for the analysis of nearly all metal ions. Because EDTA has four acidic protons, the formation of metal-ion/EDTA complexes is dependent upon the pH. For the titration of Mg2+, one must buffer the solution to a pH of 10 so that complex formation will be quantitative. WebN2 - A simple, rapid and selective complexometric method is proposed for the determination of mercury(II). Mercury(II) and other diverse associated metal ions are first complexed with excess of EDTA and the surplus EDTA is back titrated with standard zinc sulfate solution at pH 5.0-6.0 (hexamine buffer) using xylenol orange as indicator.
