Copper sulfate is blue crystal granular, soluble in water and diluted acetic acid. The solution appears as weak acidity. It will be effloresces slowly in dry air, and its surface will become white powder substance.

Copper sulfate will lose four crystal water when heated to 110 °C, and will be changed into white Copper sulfate anhydrous which is easy to absorb water when the temperature is higher than 200°C.

1) Flotation reagent in mining industry;electroplating industry;reagent in the preparation of dyestuffs intermediates;mordant in dyeing;preservative of wood etc.

2) Widely used in feed industry as feed additive;Correction of copper deficiency in animals;Growth stimulant for fattening pigs and broiler chickens etc.

3) Widely used in agriculture as fertilizer; fungicides ;insecticides;growth stimulant for fattening pigs and broiler chickens etc

Copper Sulphate is used for extracting the other copper, is also used as a textile mordant, agricultural pesticides, fungicides, and for water treatment. As a mordant for cotton and silk; used to produce green and blue pigment; used as insectucude, bactericide for water, antiseptics for wood, catalyst for tannage, electrocopper, battery. carving and so on ; used in mining industry and as raw materials of other chemicals.

1.Used in the production of paper and cellulose pulp.

2. Used for the production of soap, synthetic detergents, synthetic fatty acids.

3. Used as cloth desizing agent, scouring agent and silk polish agent in textile printing .

4. Used in the production of borax, sodium cyanide, formic acid etc in the chemical industry.

5. It constitutes an essential reactant in the production of many useful organic chemicals (more than 30 % of caustic production goes into this application).

6. Inorganic chemicals like paints, glass and ceramics and uses in fuel cell production and cosmetics are also very important.

7. The paper, pulp and cellulose industries are major users of caustic soda.Other areas where caustic is essential are: the food industry, water treatment (for the flocculation of heavy metals and acidity control), the soaps and detergents sectors, the textile sector (as a bleaching agent), mineral oils (preparation of greases and fuel additives) and the synthesis of the synthetic fiber rayon

8. About four per cent of caustic production is used in the process of refining aluminium from its ore bauxite.

9. The remainder of the caustic production (more than 17%) has miscellaneous applications, like the synthesis of pharmaceutical compounds, rubber recycling and the neutralisation of acids.
