1. Introduction of Copper Sulfate
Copper sulfate is a kind of blue crystal granular, soluble in water and diluted acetic acid. The aqueous solution is slightly acidic and bluish. It will be effloresces slowly in dry air, and its surface will become white powder substance. Copper sulfate is also an important raw material for preparing other copper-containing compounds.

3. Application of Copper Sulfate
a. Used as an analytical reagent, such as a B solution that can be used in biology to prepare feilin reagent to identify reducing sugars and biurea reagents to identify proteins, but usually for immediate use;
b. In industry field, copper sulfate can be used in the manufacture of other copper salts such as cuprous chloride, cuprous chloride, cupric pyrophosphate, cuprous oxide, cupric acetate, cupric carbonate, and copper mono-azo dyes such as reactive brilliant blue and reactive violet
c. In coating industry, copper sulfate can be used in the production of bottom anti-fouling paint;
d. In the electroplating industry, copper sulfate can be used as the main salt and copper ion additive of total bright acid copper plating.
e. In the printing and dyeing industry, copper sulfate can be used as a mordant of mordant and fine dyeing cloth.
f. In the organic industry, copper sulfate can be used as a catalyst for the synthesis of spices and dye intermediates and as a copolymer of methyl methacrylate.Anhydrous salt is used to catalyze the transacetal reaction.Anhydrous salt reacts with potassium permanganate to form an oxidant used in the conversion of primary alcohols.
g. In the agricultural field, copper sulfate can mix with limestone water, produces bordeaux liquid, which ACTS as an antiseptic to control fungi on crops and prevent fruit rot.
h. In the breeding industry, copper sulfate can be used as the main raw material of the trace element copper for feed additive.
i. Copper sulfate also can be used for dehydrating agent for alcohols and organic compounds.Gas drying agent.
