Copper sulfate chemical formula CuSO?

Copper sulfate is a white or off-white powder. The aqueous solution is weakly acidic and shows blue color. However, when crystallized from aqueous solution, it produces blue copper sulfate pentahydrate (CuSO?-5H?O, also known as bile alum), and this principle can be used to test the presence of water. Loss of water of crystallization by heat and decomposition, at room temperature and pressure is very stable, not deliquescent, in dry air will gradually weathering.

Copper sulfate is an important raw material for the preparation of other copper-containing compounds. Mixed with lime milk can be obtained Bordeaux liquid, used as a fungicide. It is also used as an electrolyte in electrolytic refining of copper.

Copper sulfate uses

1, used as an analytical reagent, for example, can be used to configure the Ferrin reagent for the identification of reducing sugars in biology, and identification of proteins, the B solution of the urea reagent, but usually ready to use;

2, used as an analytical reagent, for example, can be used to configure the Ferrin reagent for the identification of reducing sugars and identification of proteins, but usually ready to use;

2. Used as a food grade chelating agent and clarifier in the production process of leather eggs and wine;

3. Industrial. Used in the manufacture of other copper salts such as cuprous chloride, copper chloride, copper pyrophosphate, cuprous oxide, copper acetate, copper carbonate, copper monoazo dyes such as reactive brilliant blue, reactive violet, etc.; paint industry for the production of anti-fouling paints for ship bottoms.

4, the agricultural field, mixed with lime water to generate Bordeaux liquid, as a fungicide, used to control the fungus on the crop, to prevent rotting of fruits, etc.; due to the copper ion is toxic to fish, the dosage must be strictly controlled. The aquaculture industry is also used as the main raw material for the feed additive trace element copper.

Compound chemical formula writing:

First, according to the positive before the negative after the order of all the elements that make up the compound symbols, and then in the lower right corner of each element symbol with a number of the number of atoms of the element in each compound molecule. A certain order usually means: compounds composed of the element oxygen and another element, generally to write the oxygen symbol on the right.

Compounds composed of hydrogen and another element, usually write the hydrogen symbol on the left; metal elements, hydrogen and non-metal elements, usually write the non-metal element symbol on the right. Directly by the ion composition of the compound, its chemical formula is commonly used in its ion the simplest integer ratio.
