Description and Uses

Copper(II) sulfate pentahydrate is known as blue vitriol. It is an odorless blue crystal that readily dissolves in water. It is also soluble in methanol, glycerol and slightly soluble in ethanol. The highly toxic, non-combustible has a nauseating metallic taste and turns white when dehydrated. Structurally, in the pentahydrate molecule, each copper(II) ions is surrounded by four water molecules in the corners and the fifth water molecule is attached by hydrogen bonding. Copper (II) sulfate has many applications including preparation of Bordeaux mixture, a fungicide preparation. Electroplating, timber preservation and textile industry use copper (II) sulfate.

Anhydr salt for detecting and removing trace amounts of water from alcohols and other organic Compounds; as fungicide. Pentahydrate as agricultural fungicide, algicide, bactericide, herbicide; food and fertilizer additive; in insecticide mixtures; in manufacture of other Cu salts; as mordant in textile dyeing; in preparation of azo dyes; in preserving hides; in tanning leather; in preserving wood; in electroplating solutions; as battery electrolyte; in laundry and metal-marking inks; in petroleum refining; as flotation agent; pigment in paints, varnishes and other materials; in mordant baths for intensifying photographic negatives; in pyrotechnic compositions; in water-resistant adhesives for wood; in metal coloring and tinting baths; in antirusting compositions for radiator and heating systems; as reagent toner in photography and photoengraving; etc.
