| | Cadmium sulfate Usage And Synthesis |
| Uses | Cadmium sulfate is an inorganic compound and often used in electroplating for electronic circuits. It is also used for biocatalytic etching of semiconductor cadmium sulfide nanoparticles for optical detection of analytes. In addition, Cadmium Sulfate was used to develop a DNA-based quantum dot sensor to detect ibuprofen. | | Chemical Properties | Cadmium sulfate is a white to colorless, odorless, crystalline substance. | | Chemical Properties | Cadmiumsulfate, CdS04, is an effiorescent crystalline solid that is soluble in water. It is used as an antiseptic,in the treatment of venereal diseases and rheumatism, and to detect the presence of hydrogen sulfide.
| | Physical properties | Colorless orthogonal crystal; the hydrates have monoclinic crystal system; density 4.69 g/cm3 (density of mono-, and octahydrates is 3.79 and 3.08 g/cm3, respectively); melts at 1,000°C (octahydrate decomposes at 40°C); soluble in water, insoluble in ethanol. | | Uses | Cadmium sulfate (CdS), also called “orange cadmium,” is used to produce phosphors and
fluorescent screens. It is also used as a pigment in inks and paints, to color ceramics glazes, in the
manufacture of transistors in electronics, photovoltaic cells, and solar cells, and in fireworks. | | Uses | Applied in the formation of novel two-dimensional Cd-SCN coordination solids with unusual and tailorable, checkerboard- or herringbone-patterned structures these structures are important steps toward technologically useful materials.1 | | Uses | It is a catalyst in Marsh test fir arsenic; determination of hydrogen sulfide. | | Preparation | Cadmium sulfate is prepared by the reaction of cadmium metal or its oxide or hydroxide with dilute sulfuric acid:
CdO + H2SO4 → CdSO4+ H2
CdO + H2SO4 → CdSO4 + H2O
Cd(OH)2 + H2SO4 → CdSO4+ 2H2O. | | Definition | ChEBI: Cadmium sulfate is a cadmium salt. | | General Description | Odorless white solid. Sinks and mixes slowly with water. | | 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 | | Shipping | UN2570 Cadmium compounds, Hazard Class:
6.1; Labels: 6.1-Poisonous materials, Technical Name
Required. | | 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 |
