Copper(II) sulfate Chemical Properties,Uses,Production
Chemical Properties
Cupric sulfate, a bluish crystalline powder, also known as hydrocyanite and copper sulfate, vitriol, chalcanthite, and bluestone, is an azure blue material used in the It is used in the leather industry. It is prepared by the reaction of sulfuric acid and copper. It is also obtained as a by-product from copper refineries.
Chemical Properties
Copper sulfate (anhydrous form) is green or gray-white powder, whereas pentahydrate, the most commonly encountered salt, is bright blue. The anhydrous form occurs as a rare mineral known as chalcocyanite. Hydrated copper sulfate occurs in nature as chalcanthite. Copper sulfate is made by the action of sulfuric acid with a variety of copper compounds. Copper sulfate is used in hair dyes, coloring glass, processing of leather, textiles, and in pyrotechnics as a green colorant. Copper sulfate pentahydrate is used as a fungicide and a mixture with lime is called Bordeux mixture and is used to control fungus on grapes, melons, and other berries, as a molluscicide for the destruction of slugs and snails, particularly the snail host of the liver fl uke. Copper sulfate is used in Fehling and Benedict's solution to test reducing sugars
Chemical Properties
Copper sulfate is a greenish-white crystalline solid; the pentahydrate is Blue powder or granules, or ultramarine crystalline solid.
Uses
Used as an antimicrobial and molluscicide.
Uses
Copper sulfate is also known as blue vitriol, this substance was made by the action of sulfuric acid on elemental copper. The bright-blue crystals are soluble in water and alcohol. Mixed with ammonia, copper sulfate was used in liquid filters. The most common application for copper sulfate was combining it with potassium bromide for making copper bromide bleach for intensification and toning. Some photographers used copper sulfate as a restrainer in ferrous sulfate developers that were used in the collodion process.
Uses
Copper Sulfate is a nutrient supplement and processing aid most often used in the pentahydrate form. This form occurs as large, deep blue or ultramarine, triclinic crystals, as blue granules, or as a light blue powder. The ingredient is prepared by the reaction of sulfuric acid with cupric oxide or with copper metal. May be used in infant formula. It is also termed cupric sulfate.
