General Description
Red-violet crystalline solid. Vinegar-like odor. (USCG, 1999)

Hazards

Reactivity Alerts
none
Air & Water Reactions
Water soluble. Deliquescent
Fire Hazard
Special Hazards of Combustion Products: Toxic cobalt oxide fumes may form in fire. (USCG, 1999)
Health Hazard
Inhalation causes shortness of breath and coughing; permanent disability may occur. Ingestion causes pain and vomiting. Contact with eyes causes irritation. Contact with skin may cause dermatitis. (USCG, 1999)
Reactivity Profile
Salts, basic, such as COBALT ACETATE, are generally soluble in water. The resulting solutions contain moderate concentrations of hydroxide ions and have pH's greater than 7.0. They react as bases to neutralize acids. These neutralizations generate heat, but less or far less than is generated by neutralization of the bases in reactivity group 10 (Bases) and the neutralization of amines. They usually do not react as either oxidizing agents or reducing agents but such behavior is not impossible.
