Product name: copper sulfate, anhydrous
Molecular weight: 159.608
CAS no. : 7758-99-8
Chemical formula: CuSO4
Physical properties: blue transparent crystal.
Soluble in water, slightly soluble in dilute ethanol and not soluble in anhydrous ethanol.
Anhydrous cupric sulfate as gray powder, easy bibulous become turquoise copper sulfate hydrate.
(anhydrous copper sulfate chemical formula CuSO4)
Copper sulfate under atmospheric pressure without melting point, after losing crystal water decomposition, heated under atmospheric pressure is stable, no deliquescence, gradually weathering in dry air.
Copper sulfate for blue asymmetric triclinic crystal of crystal system, specific gravity 2.29.
Stable chemical properties at room temperature, easy dissolved water, in 15 ℃ can be dissolved in water by 16.2%, its aqueous solution is blue, and acidic.
In the air for a long time will gradually lose crystal water, you become white.
Chemistry: chemical formula CuSO4 is acid its salt, because weak acid hydrolysis solution.
Strong water imbibition, absorbing water after five hydration reaction to generate the blue copper sulfate (commonly known as bluestone or blue vitriol).
(CuSO4 h2o + 5 = CuSO4 · 5 h2o) aqueous solution is blue.
Condensed the copper sulfate solution crystallization, anhydrous copper sulfate blue crystals can be obtained, commonly known as bluestone, copper vitriol, or blue vitriol (relative density 2.28, the relative molecular mass is 249.8, blue triclinic crystal, easy weathering in dry air).
When heated to 190 ℃ lose crystallization water into fourths CuSO4 · H2O (relative molecular mass is 177.62, light green powder).
To 258 degrees c into anhydrous salt often use this feature to test some liquid containing trace water in organic matter.
The bluestone heated to 650 ℃ high temperature, can be decomposed into black copper oxide, sulphur dioxide and oxygen.
All have toxic, soluble in water, insoluble in ethanol.
Under the action of air reaction with Sulfuric Acid
copper or copper oxide dissolves in dilute sulphuric acid, the evaporation and crystallization.
Used for ammonia catalyst, cotton silk mordant, wood preservatives, pesticides, fungicides, water quality medical vomiting agent: as the electroplating, dyestuffs and leather industry of raw materials, anhydrous copper sulfate is used as the dehydrating agent and gas dryer.
USES: used in the manufacture of other copper salts, such as cuprous chloride, copper chloride, pyrophosphate, cuprous oxide, copper acetate, copper carbonate, etc.
Dyes and pigments industry used in the manufacture of copper single azo dyes such as reactive brilliant blue and reactive violet.
