The titrimetric determination of chromium in the presence of excess of chloride

Abstract

Solutions of chromium(VI) that contain an excess of chloride ions can be determined by direct titration with ammonium iron(II) sulphate, with either N-phenylanthranilic acid or diphenylamine-4-sulphonic acid as indicator. Solutions of chromium(III) that contain an excess of chloride ions can be determined similarly after oxidising the chromium(III) to chromium(VI) with alkaline hydrogen peroxide.
