It is used to manufacture other feed salts, such as cuprous chloride, copper chloride, copper pyrophosphate, cuprous oxide, copper acetate, copper carbonate, etc. The dyestuff and pigment industry is used to produce copper containing monoazo dyes such as reactive brilliant blue and reactive violet. Analysis reagent copper sulfate is used in several chemical analysis. It is used for the determination of reconstituted sugars in Fehling's reagent and Bancroft's reagent.
In the reaction, Cu2 + is recovered to a univalent insoluble red precipitate cuprous oxide. Copper sulfate can also be used in biuret reagent to detect protein. Copper sulfate can be used to test anemia. If the blood sample contains enough hemoglobin, it will sink quickly; If the hemoglobin content is not enough, the blood sample will be suspended in the solution.
In the reaction of the flame, copper sulfate is blue-green, much more blue than barium ion. Organic synthesis copper sulfate can be used in organic synthesis. Anhydrous salt is used to catalyze the reaction of acetal conversion. Anhydrous salt reacts with potassium permanganate to form an oxidant for the conversion of primary alcohol. In organic industry, it is used as catalyst for synthesis of perfume and dye intermediates, and polymerization inhibitor of methyl methacrylate.
