 | Copper Sulphate Pentahydrate CuSO4.5H2O Trade Name : Copper Sulphate Pentahydrate Synonym : Copper Sulphate, copper II Sulphate, Bluestone, Blue Vitriol Formula : CuSO4.5H2O CAS No.: 7758-99-8 HS Code : 2833.25 PHYSICAL DESCRIPTION/ PROPERTIES Mol Weight : 249.68 Appearance : Transparent blue crystals, granules or powder. Odour : Odourless Melting Point : Above 100 degrees C, copper sulfate loses water from crystallization with formation of the monohydrate Boiling Point : Solubility in Water : 320 g/L (20 degree C) Density : 2.284 QUALITY INDEX Industrial Grade Purity : 96.0% min (grade 1), 93.0% min (grade 2) Water Insoluble : 0.2% max (grade 1), 0.4% max (grade 2) Free Flowing Acid : 0.1% max (grade 1), 0.2% max (grade 2) Standard : GB-437-80 (China) Animal Feed Grade Purity : 98.5% min Cu : 24% min Water Insoluble : 0.2% max As : 5 ppm max Heavy Metal (Pb) : 10 ppm max Standard : GB-8249-87(China) Electroplating Grade Purity : 98.0% min Cu : 24.9% min Water Insoluble : 0.2% max Co : 0.02% max Sb : 0.006% max Fe : 0.25% max As : 0.006% max Cl : 0.02% max Pb : 0.006% max Ni : 0.02% max Standard : DIN 50972(China) APPLICATION It can be used to plate metals with copper, as a fungicide or herbicide, or as a chemical test for water (the anhydrous form will absorb water, turning blue). Mixed with lime it is called Bordeaux mixture. It is also used, in Fehling's solution, to test for reducing sugars, which reduce the blue Cu2+aq ions to red copper(I) oxide. Still other uses include hair dyes and the processing of leather and textiles. Copper sulfate is also used to test blood for anemia. A drop of the patient's blood is dropped into a container of copper sulfate, if it sinks within a certain time, then the patient has sufficient haemogloblin levels and is not anemic. If the blood floats or sinks too slowly, then the patient is iron-deficient and may be anemic. In a flame test, copper ions emit a deep blue-green light, much more blue than the flame test for barium. TOXICITY Copper sulphate is a powerful oxidizing agent and irritant to mucous membranes. A dose-response effect following ingestion is difficult to define but approximately 10 g may be fatal in an adult (Akintonwa et al, 1989). Chronic inhalation of copper sulphate-containing pesticides produces pulmonary and hepatic toxicity. Copper sulphate contact sensitivity is recognized.
