Preparation
Cadmium sulfate is prepared by the reaction of cadmium metal or its oxide or hydroxide with dilute sulfuric acid:CdO + H2SO4 → CdSO4+ H2CdO + H2SO4 → CdSO4 + H2OCd(OH)2 + H2SO4 → CdSO4+ 2H2O.
Air & Water Reactions
Water soluble.
Reactivity Profile
Cadmium sulfate acts as a weakly acidic inorganic salt, which is soluble in water. The resulting solutions contain moderate concentrations of hydrogen ions and have pH's of less than 7.0. They react as acids to neutralize bases. These neutralizations generate heat, but less or far less than is generated by neutralization of inorganic acids, inorganic oxoacids, and carboxylic acid. They usually do not react as either oxidizing agents or reducing agents but such behavior is not impossible. Many of these compounds catalyze organic reactions.
Hazard
A confirmed carcinogen.
Health Hazard
Inhalation may cause dryness of throat, coughing, constriction in chest, and headache. Ingestion may cause salivation, vomiting, abdominal pains, or diarrhea. Contact with eyes causes irritation.
Health Hazard
Exposures to cadmium salts by absorption are most effi cient via the respiratory tract. The
symptoms of health effects include, but are not limited to, irritation, headache, metallic
taste, and/or cough. Severe exposures cause shortness of breath, chest pain, and fl u-like
symptoms with weakness, fever, headache, chills, sweating, nausea and muscular pain,
pulmonary edema, liver and kidney damage, and death. Prolonged exposures, even at
relatively low concentrations, may result in kidney damage, anemia, pulmonary fi brosis,
emphysema, perforation of the nasal septum, loss of smell, male reproductive effects, and
an increased risk of cancer of the lung and of the prostate. Decrease in bone density, renal
stones, and other evidence of disturbed calcium metabolism have been reported.
Fire Hazard
Special Hazards of Combustion Products: Toxic cadmium oxide fume may form in fires.
Safety Profile
Confirmed human
carcinogen with experimental carcinogenic
data. Poison by ingestion, subcutaneous, and
intraperitoneal routes. Experimental
teratogenic and reproductive effects.
Mutation data reported. See also
CADMIUM COMPOUNDS and
SULFATES. When heated to
decomposition it emits very toxic fumes of
Cd and SOx.
Potential Exposure
It is used in pigments, electroplating;
as a fungicide; and in synthetic and analytical chemistry.
Also used in fluorescent screens; as an electrolyte.
Incompatibilities: Acts as a weak inorganic acid; neutralizes bases. 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, sulfur, selenium, tellurium, zinc

Precautions
Cadmium compounds cause more health disorders to occupational workers and persons
with pre-existing skin disorders, eye problems, blood disorders, prostate problems, or
impaired liver, kidney, or respiratory function. These workers are more susceptible to the
effects of cadmium salts. On contact with cadmium, exposed workers should wash the
skin and eyes immediately with plenty of water
Check Digit Verification of cas no
The CAS Registry Mumber 10124-36-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,0,1,2 and 4 respectively; the second part has 2 digits, 3 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 10124-36:
(7*1)+(6*0)+(5*1)+(4*2)+(3*4)+(2*3)+(1*6)=44
44 % 10 = 4
So 10124-36-4 is a valid CAS Registry Number.
