Physical Description
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.
Chromosulfuric acid is a colorless, oily liquid. It is soluble in water with the release of heat. It is corrosive to skin and metals.
