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

Acidic organic/inorganic salts, such as CHROMIC SULFATE, are generally soluble in water. The resulting solutions contain moderate to high concentrations of hydrogen ions and have pH's of less than 7.0. They react as acids to neutralize bases. These neutralizations generate heat, but less or far less than is generated by neutralization of inorganic acids, inorganic oxoacids, and carboxylic acid. They usually do not react as either oxidizing agents or reducing agents but such behavior is not impossible. Many of these compounds catalyze organic reactions.
