COPPER SULPHATE
Copper sulphate, blue stone, blue vitriol are all common names for pentahydrated cupric sulphate, CuSO₄5H₂O, which is the best known and the most widely used of the copper salts. Indeed it is often the starting raw material for the production of many of the other copper salts. Today in the world there are more than 100 manufacturers and the world's consumption is around 200,000 tonnes per annum of which it is estimated that approximately three-quarters is used in agriculture, principally as a fungicide.
Copper forms compounds in the oxidation states +1 and +2 ( trivalent copper survives no more than a few seconds in an aqueous solution). Copper sulfate is the common name for the blue crystalline cupric sulfate, in which copper has valence +2. It may also refer to cuprous sulfate (Cu₂SO₄), in which copper has valence +1.
