Description and Uses
Copper sulfate is a greenish-white crystallinesolid; the pentahydrate is blue powder or granules, or ultramarine crystalline solid. Molecular weight =159.60; 249.70(pentahydrate). Boiling point =150℃ (pentahydrate) with25H2O; Melting point = (decomposes) .200℃; decomposes .110℃ (pentahydrate) with 24H2O; copper sulfatedecomposes to CuO at 650℃. Hazard Identification (basedon NFPA-704 M Rating System): Health 2, Flammability 0,Reactivity 0. Highly soluble in water; forms a bright bluesolution.
Copper Sulfate is a nutrient supplement and processing aid most often used in the pentahydrate form. This form occurs as large, deep blue or ultramarine, triclinic crystals, as blue granules, or as a light blue powder. The ingredient is prepared by the reaction of sulfuric acid with cupric oxide or with copper metal. May be used in infant formula. It is also termed cupric sulfate.
