Determination of Chromic Acid in Chromium Plating Solutions Using a Redox Titration and Indicator

Abstract

The chemical literature lacks a simple analytical method for adequately controlling chromic acid in chromium plating solutions during the plating process. In this report, a simple method for analyzing and controlling chromic acid during the plating process is presented. The optimum operating range of chromic acid is 240 to 260 g/l and the resulting precisions are in the range of 0 to 2.5 g/l, providing adequate control of these plating solutions supported by five years of testing.
