Cadmium acetate is a chemical compound with the formula Cd(CH3COO)2. This colorless solid is classified as coordination polymer, featuring acetate ligands interconnecting cadmium centers. Cadmium acetate exists in anhydrous form and as dihydrate, Cd(CH3COO)2·2H2O.
Thermal decomposition of cadmium acetate gives cadmium oxide.
Cadmium acetate is a colorless crystalline solid, with a slight vinegar-like smell. It is soluble in water and primary alcohols.
Cadmium acetate is sold by chemical suppliers. It can sometimes be found on eBay.
Cadmium acetate is Group 1 carcinogens by the IARC, making it difficult to acquire in many countries.
- CdO + 2 CH3COOH → Cd(CH3COO)2 + H2O
Concentrating the solution and cooling it will cause crystals to form.
Cadmium acetate is extremely toxic and is classified as Group 1 carcinogen. Wear proper protection when handling it.
Cadmium acetate should be stored in closed bottles, in well ventilated places.
Should be converted to an insoluble cadmium compound, such as cadmium sulfide and taken to hazardous waste disposal centers.
