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.

Properties

Chemical

Thermal decomposition of cadmium acetate gives cadmium oxide.

Physical

Cadmium acetate is a colorless crystalline solid, with a slight vinegar-like smell. It is soluble in water and primary alcohols.

Availability

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.

Preparation

Cadmium acetate can be obtained by treating cadmium oxide with acetic acid:

CdO + 2 CH3COOH → Cd(CH3COO)2 + H2O

Concentrating the solution and cooling it will cause crystals to form.

Projects

  • Make CdO nanoparticles[1][2]
  • Electroplate cadmium metal

Handling

Safety

Cadmium acetate is extremely toxic and is classified as Group 1 carcinogen. Wear proper protection when handling it.

Storage

Cadmium acetate should be stored in closed bottles, in well ventilated places.

Disposal

Should be converted to an insoluble cadmium compound, such as cadmium sulfide and taken to hazardous waste disposal centers.
