Useful:

• Chemical Classes: Metals -> Cadmium Compounds, Inorganic
• Canonical SMILES: CC(=O)[O-].CC(=O)[O-].[Cd+2]
• Inhalation Risk: A harmful concentration of airborne particles can be reached quickly when dispersed, especially if powdered.
• Effects of Long Term Exposure: The substance may have effects on the kidneys and bones. This may result in kidney impairment and osteoporosis (bone weakness). This substance is carcinogenic to humans.
• Description: Cadmium acetate is a colourless crystal with a characteristic odour. It is not combustible, but it decomposes on heating, producing toxic fumes of cadmium oxide. It is incompatible with oxidising agents, metals, hydrogen azide, zinc, selenium, and tellurium. Occupational exposure to cadmium and cadmium compounds occurs in workplaces mainly in the form of airborne dust and fume. Occupations and workplaces include cadmium production and refining, nickel–cadmium battery manufacture, cadmium pigment manufacture and formulation, cadmium alloy production, mechanical plating, zinc smelting, soldering, and polyvinylchloride compounding. Cadmium and compounds enter the body mainly by inhalation and by ingestion.
• Physical properties: The anhydrous salt occurs as a colorless crystal while the dihydrate is a white crystalline solid; faint odor of acetic acid; density 2.34 g/cm3 (dihydrate2.01 g/cm3); melts at 255°C; dihydrate decomposes at 130°C; soluble in water and ethanol; pH of 0.2M aqueous solution 7.10.
• Uses: Cadmium acetate is used for glazing ceramics and pottery; in electroplating baths; in dyeing and printing textiles; and as an analytical reagent for sulfur, selenium, and tellurium. Cadmium(II) acetate can be used in the synthesis of cadmium oxide (CdO) thin films, which find usage in gas sensors, phototransistors, and diodes. It can also be used in the synthesis of cadmium sulfide (CdS) nanoparticles, which can be used in a variety of optoelectronic devices.
