CHROMIUM(II) CHLORIDE Usage And Synthesis

Chemical Properties	grey green powder
Uses	The vapor-phase co-reductions with other metal halides by hydrogen results in finely divided intermetallics with applications as structural materials or compounds with useful thermoelectric, magnetic, and oxidation-resistance properties.
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. CHROMIUM(II) CHLORIDE is used to make other chemicals and as an oxygen absorbent.
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.
Reactivity Profile	Inorganic reducing agents, such as CHROMIUM(II) 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 CHROMIUM(II) 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].
Health Hazard	DUST: Harmful if inhaled. SOLID: Irritating to skin and eyes. Harmful if swallowed.
