Copper sulfate is one of the most important copper salts, which is widely used in electroplating, printing and dyeing, pigment, pesticide and so on.Inorganic pesticide Bordeaux mixture is a mixture of copper sulphate and lime milk. It is a good fungicide and can be used to prevent and cure diseases of many crops.In bordeaux, France in 1878, the vine disease occurred most of the dead, and the trees on both sides of the road, afraid of pedestrians to pick to eat on the trunk with quick lime and copper sulfate solution, the trunk gray, dare not eat pick pedestrians looked uncomfortable, the tree did not die, knows the mixture with sterilization ability, the further study called bordeaux mixture.For bordeaux mixture, the ratio of copper sulfate to quick lime (preferably fresh lime in bulk) is usually 1∶1 or 1∶2. The amount of water used is also determined by the different crops, the absence of disease and seasonal temperature.The best preparation is the "two-liquid method," in which copper sulfate and quicklime are mixed with half the required amount of water, respectively, and then poured simultaneously into another container, stirring constantly, to obtain a sky-blue colloidal solution.Bordeaux mixture should be used now, because the gelatinous particles will gradually become larger and sink over a long period of time, reducing the efficacy.Copper sulfate is also used to prepare other copper compounds and electrolytes used in copper refining.Anhydrous copper sulphate can be produced by concentrating and crystallizing copper oxide with sulfuric acid or copper with concentrated sulfuric acid.Anhydrous copper sulfate can be prepared by oxidizing copper with concentrated sulfuric acid in the laboratory.
