What is Copper Sulfate
Copper sulphate it's pentahydrate is also known as blue alum or bile alum. Copper sulphate is also often used as shorthand for copper sulphate crystals pentahydrate.
Dark blue large granular crystals or blue granular crystalline powder. Toxic, odorless, with metallic astringent taste. Density 2.2844g/cm^3, weathering slowly in dry air. Soluble in water, aqueous solution is weakly acidic, insoluble in ethanol. 258 ° C or more will lose all the water to crystallize into a white powder anhydrous copper sulfate, 650 ° C is decomposed into copper oxide and sulfur trioxide. Anhydrous copper sulfate has strong water absorption, put it into 95% ethanol or water-containing organic matter, that is, absorb water and return to blue crystals. Copper ions in copper sulfate can destroy the three-dimensional structure of proteins and denature them. When determining the concentration of proteins, it is common to add alkali to the protein, and then add copper sulfate solution, at which time the solution will turn purple, a reaction known as the double urea reaction.

Application areas of Copper Sulfate
Inorganic industry for the manufacture of other copper salts. Dyestuff and pigment industry for the manufacture of copper-containing monoazo dyes. It is used as a catalyst for synthesizing spices and dye intermediates, and as a polymerization inhibitor for methyl methacrylate in organic industry. It is used as a fungicide in the production of anti-fouling paint for ship bottoms in the paint industry. It is used as the main salt of full bright acid copper plating and copper ion additive in electroplating industry. Printing and dyeing industry as mordant and fine dyed cloth oxygenating agent. Used as fungicide in agriculture.
