| Hazard Information | Back Directory | 【General Description】
A white crystalline solid. The primary hazard is the threat to the environment. Immediate steps must be taken to prevent its spread to the environment. CHROMOUS CHLORIDE(10049-05-5) is used to make other chemicals and as an oxygen absorbent. | 【Reactivity Profile】
Inorganic reducing agents, such as CHROMOUS CHLORIDE, react with oxidizing agents to generate heat and products that may be flammable, combustible, or otherwise reactive. Their reactions with oxidizing agents may be violent. Long storage of a chromous chloride solution culminated in an explosion. This was ascribed to the slow buildup of hydrogen gas that was produced by reduction of water by the Cr(II) ion [MCA Case History No. 1660]. | 【Air & Water Reactions】
Stable in dry air, but oxidizes rapidly in moist air or standing water with liberation of Hydrogen, [Merck, 11th ed., 1989]. Soluble in water. | 【Health Hazard】
DUST: Harmful if inhaled. SOLID: Irritating to skin and eyes. Harmful if swallowed. |
