Copper Sulfate

Model: 97 Percent Product Name: copper sulfate Content =: 97 Percent size: 20-120 (mesh) Use level: feed grade content: Cu = 25 The factory specializing in the production of crystal` copper sulfate, copper sulfate powder. Chemical English Name: copper sulfate Commonly known as the crystal`line hydrate: blue, blue vitriol Molecular formula: CuSO4 (pure), CuSO4 5H2O (hydrate) Molecular weight: 159.68 With the appearance of the characters: blue three triclinic crystal`. PH:3.5 The melting point (:200 ) (anhydrous) Boiling point (c): high temperature decomposition Relative density (=1):2.28 Solubility: soluble in water, 25 for 23.05g solubility in water, soluble in dilute ethanol, not soluble in ethanol, ethyl ether, liquid ammonia. Main uses: used for producing other copper salt, also used as textile mordant, insecticide, fungicide, and used for the copper. Copper sulfate (Copper sulphate) - also called blue or blue hydrate. Copper sulfate is often as crystal` copper sulfate five hydrated referred to as. Copper sulfate CuSO4.H2O with molecular weight of 160 (copper sulfate crystal`: CuSO4 5H2O with molecular weight of 249.68) Dark blue large granular crystal`s or blue granular crystal`line powder. Poison`ous, odorless, with a metallic taste. The density of 2.2844g / cm^3. The dry air will slow weathering. Soluble in water, weak acidity of the aqueous solution (288K solution, CuSO4 pH 0.1mol/L = 4.2), insoluble in ethanol. The crystal` is heated will lose water of crystal`lization, 45 lose two molecules of water of crystal`lization, 110 lose four molecules of water of crystal`lization, 258 will lose all water crystal`lization become `ed anhydrous copper sulfate, 650 is decomposed into three copper oxide and sulfur dioxide. Anhydrous copper sulfate have a strong water absorption, put it into 95 Percent ethanol or aqueous organic matter, namely, moisture absorption and recovery for the blue crystal`. The three-dimensional structure of the copper ions in copper sulfate can damage proteins, denature. Determination of protein concentration often add alkali in protein, adding copper sulfate solution, the solution will become purple. At this time, the reaction is called biuret reaction. Anhydrous copper sulfate is white powder` density of 3.603 g / cm 25 solubility in water is 23.05 grams per 100 grams of water, insoluble in ethanol or ether strong absorbent, water after the blue. Copper sulfate is heated to 650 into CuO:
