CHEMICAL AND PHYSICAL PROPERTIES

Physical 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.
Color/Form Exists in two crystalline forms, alpha (wurtzite) and beta (sphalerite)
Solubility Solubility: 40 g/ 100 g water at 25 °C; 67 g/100 g water at 100 °C; 3 g/ 100 g alcohol at 25 °C /Zinc acetate dihydrate/
Density 1.74 at 68 °F (USCG, 1999) - Denser than water; will sink
Decomposition When heated to decomposition it emits toxic fumes of /zinc oxide/.
pH Between 6,0 and 8,0 (5 % solution)
Other Experimental Properties Changes to alpha form at 1020 °C; sublimes at 1180 °C /beta/
Chemical Classes Metals -> Organic Acids, Metal Salts
