General Description
Obtained in both anhydrous form and as a dihydrate. Both are white crystalline solids. The primary hazard is the threat posed to the environment. Immediate steps should be taken to limit spread to the environment. Used to preserve wood, to make other zinc compounds, as a food and feed additive.

Hazards

Reactivity Alerts
none
Air & Water Reactions
Water soluble.
Fire Hazard
No information available.
Health Hazard
Inhalation causes mild irritation of nose and throat, coughing, and sneezing. Ingestion can cause irritation or corrosion of the alimentary tract, resulting in vomiting. Contact with dust causes irritation of eyes and mild irritation of skin. (USCG, 1999)
Reactivity Profile
Salts, basic, such as ZINC 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.
