Mineral Grade Copper Sulfate
Chemical formula: CuSO4 5H2O Molecular weight: 249.68 CAS: 7758-99-8
The common form of copper sulfate is crystal, copper sulfate monohydrate tetrahydrate ([Cu(H2O)4]SO4·H2O, copper sulfate pentahydrate), which is a blue solid. Its aqueous solution appears blue due to hydrated copper ions, so anhydrous copper sulfate is often used to test the presence of water in the laboratory. In real production and life, copper sulfate is often used to refine refined copper, and it can be mixed with slaked lime to make Bordeaux mixture, a pesticide.
