hexavalent chromium is much more toxic than triangular chromium. In industrial plants, the toxicity of the chromium is reduced by the reaction below (only the ions involved are included): b) Write the partial reactions for the reduction and oxidation c) balance the redox equation. The reaction occurs in an acid environment Please show steps and explain :) CrO2- + HSO3- → Cr3+ + SO2-
