Industries and functions

How it is made

Action of sulfuric acid on chromium hydroxide with subsequent crystallization.

Mixtures of basic chromic sulfates (containing mainly Cr(OH)S04)with sodium sulfate are produced commercially by the organic reduction (with such substances as molasses) of a solution of sodium dichromate in the presence of sulfuric acid or by reduction of dichromate solutions with sulfur dioxide

Solutions of mixed hydrated chromic sulfates are obtained by dissolving hydrous chromic oxide in concentrated sulfuric acid and allowing it to stand until crystals of the hydrated chromic sulfate separate. The anhydrous form is produced by heating any of the hydrates to 400 °C in air or to 280 °C in a stream of carbon dioxide.
