Chemische Eigenschaften
Cupric sulfate, a bluish crystalline powder, also known as hydrocyanite and copper sulfate, vitriol, chalcanthite, and bluestone, is an azure blue material used in the It is used in the leather industry. It is prepared by the reaction of sulfuric acid and copper. It is also obtained as a by-product from copper refineries.
Verwenden
Copper(II) sulfate may be employed for the following studies:
- As a catalyst for the acetylation of alcohols and phenols under solvent-free conditions.
- To compose the electrolyte for the electrodeposition of Cu-Zn-Sn precursors, required for the preparation of Cu2ZnSnS4 (CZTS) thin films.
- As a Lewis acid catalyst for the dehydration of alcohols.5
Definition
A compound prepared as the hydrate by the action of dilute sulfuric acid on copper( II) oxide or copper(II) carbonate. On crystallization, blue triclinic crystals of the pentahydrate (blue vitriol, CuSO
4.5H
2O) are formed. Industrially copper(II) sulfate is prepared by passing air through a hot mixture of dilute sulfuric acid and scrap copper. The solution formed is recycled until the concentration of the copper(II) sulfate is sufficient. Copper(II) sulfate is readily soluble in water. The monohydrate (CuSO
4.H
2O) is formed at 100°C and the anhydrous salt at 250°C. Anhydrous copper( II) sulfate is white; it is extremely hygroscopic and turns blue on absorption of water. It decomposes on heating to give copper(II) oxide and sulfur(VI) oxide.
Copper(II) sulfate is used as a wood preservative, a fungicide (in Bordeaux mixture), and in the dyeing and electroplating industries.
Allgemeine Beschreibung
A white or off-white solid. Melting point 200°C with decomposition. Non-combustible.
Air & Water Reaktionen
Soluble in water.
Reaktivität anzeigen
Anhydrous Cupric sulfate serves as a weak oxidizing agent. Causes hydroxylamine to ignite. Gains water readily. The hydrated salt is vigorously reduced by hydroxylamine [Mellor 8:292(1946-1947)]. Both forms are incompatible with finely powdered metals. Both are incompatible with magnesium, corrode steel and iron, may react with alkalis, phosphates, acetylene gas, hydrazine, or nitromethane, and may react with beta-naphthol, propylene glycol, sulphathiazole and triethanolamine if the pH exceeds 7 . Both act as acidic salts, corrode metals and irritate tissues.
Hazard
Toxic; highly irritant.
Health Hazard
INGESTION: copper sulfate may induce severe gastroenteric distress (vomiting, gastroenteric pain, and local corrosion and hemorrhages), prostration, anuria, hematuria, anemia, increase in white blood cells, icterus, coma, respiratory difficulties, and circulatory failure.
Landwirtschaftliche Anwendung
Fungicide, Algaecide, Bactericide, Herbicide,
Molluscicide: Copper sulfate is a fungicide used to control bacterial and fungal diseases of fruit, vegetable, nut, and
field crops. These diseases include mildew, leaf spots,
blights, and apple scab. It is used as a protective fungicide
(Bordeaux mixture) for leaf application and seed treatment. It is also used as an algaecide and herbicide, and
to kill slugs and snails in irrigation and municipal water
treatment systems. It has been used to control Dutch elm
disease. It is available as a dust, wettable powder, or liquid
concentrate. Used as a fungicide and algaecide, in veterinary medicine and others. Copper sulfate is also used todetect and to remove trace amounts of water from alcohols
and organic compounds.
Industrielle Verwendung
Copper sulfate (CuSO
4·5H
2O) is widely used as an activator for sphalerite, pyrite,
pyrrhotite and other sulfides during processing of base metal ores. During flotation of
some silicate minerals, copper sulfate is used as depressant, e.g. zirconium.
In manufacturing copper sulfate, sulfuric acid and scrap copper metal are used. The
process is based on the oxidation of metal and dissolution with H2SO4 according to the
following reaction:
4Cu + O
2 = 2Cu

läuterung methode
After adding 0.02g of KOH to a litre of nearly saturated aqueous solution of the sulfate, it is left for two weeks, then the precipitate is filtered on to a fibreglass filter with pore diameter of 5-15 microns. The filtrate is heated to 90o and allowed to evaporate until some CuSO4.5H2O crystallises out. The solution is then filtered hot and cooled rapidly to give crystals which are freed from mother liquor by filtering under suction [Geballe & Giauque J Am Chem Soc 74 3513 1952]. Alternatively crystallise the sulfate from water (0.6mL/g) between 100o and 0o. The pentahydrate is slowly efflorescent, losing 2H2O at 30o, two more H2O are lost at 110o and a white anhydrous powder (dessicant) is obtained on heating above 250o.
Inkompatibilitäten
Aqueous solution is an acid. May form explosive materials on contact with acetylene and nitromethane. Incompatible with strong bases; hydroxylamine, magnesium; zirconium, sodium hypobromite, hydrazine.
Waste disposal
Copper-containing soluble wastes can be concentrated through the use of ion exchange, reverse osmosis, or evaporators to the point where copper can be electrolytically removed and sent to a reclaiming firm. If recovery is not feasible, the copper can be precipitated through the use of caustics and the sludge deposited in a chemical waste landfill Add soda ash to waste CuSO4 solution; let stand 24 hours. Decant and neutralize solution before flushing to sewer. Landfill sludge.
Vorsichtsmaßnahmen
During handling and use of copper sulfate, students and occupational workers should
wear safety glasses and should not breathe the material in powder form. Copper sulfate is an environmental pollutant and must be carefully incorporated when used in its varied
applications. Workers should wear protective clothing, goggles, impermeable gloves, and
rubber boots to avoid skin contact
