| Chemical Properties | Back Directory | [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. | [Appearance]
Cadmium acetate is a colorless crystalline
solid; freezing/melting point 5 130C. Hazard identification

Odorless colorless solid. Sinks and mixes with water. | [Reactivity Profile]
Salts, basic, such as CADMIUM ACETATE(543-90-8), are generally soluble in water. The resulting solutions contain moderate concentrations of hydroxide ions and have pH's greater than 7.0. They react as bases to neutralize acids. These neutralizations generate heat, but less or far less than is generated by neutralization of the bases in reactivity group 10 (Bases) and the neutralization of amines. They usually do not react as either oxidizing agents or reducing agents but such behavior is not impossible. Special Hazards of Combustion Products: Toxic cadmium oxide fumes may form in fires [USCG, 1999]. | [Air & Water Reactions]
Slowly oxidized by moist air to form cadmium oxide [Merck 11th ed. 1989]. Water soluble. | [Health Hazard]
Exposures to cadmium acetate cause cough, skin redness, abdominal pain, nausea, vomiting, salivation, choking, dizziness, and diarrhea. On catching fi re, cadmium acetate gives
off irritating or toxic metal oxide fumes. Inhalation of dust produces perforation of the
nasal septum, loss of smell, irritation, headache, metallic taste, and cough. Prolonged
exposures to cadmium acetate may produce shortness of breath, chest pain, and fl u-like
symptoms, chills, weakness, fever, muscular pain, pulmonary edema, liver and kidney
damage and death. Cadmium acetate may have effects on the kidneys and bones, leading
to kidney impairment and osteoporosis (bone weakness), and liver damage. Accidental
ingestion or inhalation of cadmium acetate may be fatal to workers | [Health Hazard]
Inhalation causes coughing, sneezing, symptoms of lung damage. Ingestion produces severe toxic symptoms; both kidney and liver injuries may occur. Contact with dust causes eye irritation. | [Potential Exposure]

Special Hazards of Combustion Products: Toxic cadmium oxide fumes may form in fires. | [First aid]
Move victim to fresh air. Call 911 or emergency
medical service. Give artificial respiration if victim is not
breathing. Do not use mouth-to-mouth method if victim
ingested or inhaled the substance; give artificial respiration with the aid of a pocket mask equipped with a one-way
valve or other proper respiratory medical device.
Administer oxygen if breathing is difficult. Remove and
isolate contaminated clothing and shoes. In case of contact
with substance, immediately flush skin or eyes with running water for at least 20 minutes. For minor skin contact,
avoid spreading material on unaffected skin. Keep victim
warm and quiet. Effects of exposure (inhalation, ingestion,
or skin contact) to substance may be delayed. Ensure that
medical personnel are aware of the material(s) involved
and take precautions to protect themselves. Medical observation is recommended for 24 to 48 hours after breathing
overexposure, as pulmonary edema may be delayed. As
first aid for pulmonary edema, a doctor or authorized paramedic may consider administering a drug or other inhalation therapy.

UN2570 Cadmium compounds, Hazard Class:
6.1; Labels: 6.1-Poisonous materials, Technical Name
Required. | [Incompatibilities]
Compounds of the carboxyl group react
with all bases, both inorganic and organic (i.e., amines)
releasing substantial heat, water, and a salt that may be
harmful. Incompatible with arsenic compounds (releases
hydrogen cyanide gas), diazo compounds, dithiocarbamates, isocyanates, mercaptans, nitrides, sulfides (releasing
heat, toxic, and possibly flammable gases), thiosulfates,
and dithionites (releasing hydrogen sulfate and oxides of
sulfur). Incompatible with oxidizers (chlorates, nitrates,
peroxides, permanganates, perchlorates, chlorine, bromine,
fluorine, etc.); contact may cause fires or explosions. Keep
away from alkaline materials, strong bases, strong acids,
oxoacids, epoxides | [Waste Disposal]
Precipitation as sulfide, drying and return to supplier. Incineration is not
recommended.
| [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(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. | [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. | [Preparation]
Cadmium acetate is prepared by treating cadmium oxide with acetic acid:
CdO + 2CH3COOH → (CH3COO)2Cd + H2O
Also, the compound may be prepared by treating cadmium nitrate with acetic anhydride. | [storage]
Color Code—Blue: Health Hazard: Store in asecure poison location. Prior to working with Cadmiumacetate you should be trained on its proper handling andstorage. Store in tightly closed containers in a cool, wellventilated area away from heat and incompatible materialslisted above. A regulated, marked area should be established where this chemical is handled, used, or stored incompliance with OSHA Standard 1910.1045. |
