Abstract
Abstract The simultaneous volumetric determination of zinc and magnesium using disodium dihydrogen ethylenediamine tetra-acetate (complexone III) is detailed. Selective control of the pH at 6.8 enables zinc alone to be titrated, whilst magnesium is subsequently titrated at pH 10 on the same solution. Solochrome Black is used as indicator for both titrations.
