Chromic sulfate is a dark green to violet crystalline material. Used in paints and inks, ceramics, and in textile dyeing. It is noncombustible. The primary hazard of this material is the potential for environmental damage if released. Immediate steps should be taken to limit its spread to the environment.

In basic solution, Cr(III) is readily oxidized to chromium oxide (CrO4(-2)) by hypochlorite, hypobromite, peroxide, & oxygen under pressure at high temperature. In acid solution, Cr(III) is difficult to oxidize & needs strong oxidizing agents, such as concentrated perchloric acid, sodium bismuthate, & permanganate. /Trivalent chromium/|For more Other Experimental Properties (Complete) data for CHROMIUM (III) SULFATE (8 total), please visit the HSDB record page.

Water soluble.

Salts, Acidic

Chromic sulfate has weak oxidizing or reducing powers. Redox reactions can however still occur. The majority of compounds in this class are slightly soluble or insoluble in water. If soluble in water, then the solutions are usually neither strongly acidic nor strongly basic. These compounds are not water-reactive.
