With increasing amount of sulphate in the solution, less chromium is immobilized in the hydration products. But in the presence of chromate chromium-bearing ettringite-like structure phase is formed first. This is the reason why the reduction of hexavalent chromium is needed. Ferrous sulphate is the most used reduction substance.
