CHEMICAL AND PHYSICAL PROPERTIES
| 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. |
|---|---|
