Infobox references

Cadmium acetate is the chemical compound with the formula Cd(CH3CO2)2. This colourless solid is classified coordination polymer, featuring acetate ligands interconnecting cadmium centers. The compound exists in anhydrous form and as a dihydrate. It forms by treating cadmium oxide with acetic acid:[3][4]

CdO + 2 CH3COOH → Cd(CH3COO)2 + H2O

Uses[]

Cadmium acetate is used for glazing ceramics and pottery; in electroplating baths, in dyeing and printing textiles; and as an analytic reagent for sulfur, selenium and tellurium.[4]

Preparation[]

Cadmium acetate is prepared by treating cadmium oxide with acetic acid. The compound may also be prepared by treating cadmium nitrate with acetic anhydride.[5]

Safety[]

Cadmium compounds are considered Group 1 carcinogens by the IARC.
