CUPRIC SULFATE

CAS NO:7758-99-8
EC NO:231-847-6

Cupric sulfate is a salt formed by treating cupric oxide with sulfuric acid.
Cupric sulfate forms as large, bright blue crystals containing five molecules of water (CuSO4∙5H2O) and is known in commerce as blue vitriol. The anhydrous salt is produced by heating the hydrate to 150 °C (300 °F).
Cupric sulfate is utilized chiefly for agricultural purposes, as a pesticide, germicide, feed additive, and soil additive. Among its minor uses are as a raw material in the preparation of other copper compounds, as a reagent in analytic chemistry, as an electrolyte for batteries and electroplating baths, and in medicine as a locally applied fungicide, bactericide, and astringent.

Cupric sulfate, also known as copper sulphate, are the inorganic compounds with the chemical formula CuSO4(H2O)x, where x can range from 0 to 5. The pentahydrate (x = 5) is the most common form. Older names for this compound include blue vitriol, bluestone,vitriol of copper,and Roman vitriol.

The pentahydrate (CuSO4·5H2O), the most commonly encountered salt, is bright blue. Cupric sulfate exothermically dissolves in water to give the aquo complex [Cu(H2O)6]2+, which has octahedral molecular geometry. The structure of the solid pentahydrate reveals a polymeric structure wherein copper is again octahedral but bound to four water ligands. The Cu(II)(H2O)4 centers are interconnected by sulfate anions to form chains.Anhydrous copper sulfate is a light grey powder.

Description:Blue powder

Cupric Sulfate is an inorganic compound that combines copper and sulfate. In its liquid or powdered form it’s most commonly called basic copper sulfate, BSC copper fungicide, CP basic sulfate, or tri-basic copper sulfate. In its solid, crystal-shaped stone form (known as a pentahydrate) it’s known as blue stone or blue vitriol for its blue color. In this form, it’s a popular raw material for producing other types of copper salts.

Cupric Sulfate is also used in order to help with public health and safety. Cupric Sulfate destroys algae and bacteria caused by growing algae in swimming pools in addition to preventing athlete’s foot, a fungal infection that grows in between the toes in warm climates (such as an indoor swimming pool). This is done by mixing it into the flooring mixtures of showers, locker rooms, and swimming pools to prevent the bacteria from being able to live on the flooring indefinitely.

Copper sulfate is a term that can refer to either of the following chemical compounds – cuprous sulfate (Cu2SO4), or cupric sulfate (CuSO4). However, the latter is the preferred compound described by the term ‘copper sulfate’. The systematic name for CuSO4 is copper(II) sulfate, but it is also referred to as blue vitriol, Roman vitriol, the vitriol of copper, and bluestone.

The most common form of copper sulfate is its pentahydrate, given by the chemical formula CuSO4.5H2O. This form is characterized by its bright blue colour. However, it can be noted that the anhydrous form of this salt is a powder that is white.

The CuSO4 molecule consists of an ionic bond between the copper cation (Cu2+) and the sulfate anion (SO42-). An illustration describing the structure of a copper sulfate molecule is provided below.

Cupric Sulfate can be prepared by treating metallic copper with heated and concentrated sulphuric acid, or by treating the oxides of copper with dilute sulphuric acid.
Cupric Sulfate can be noted that the oxidation state exhibited by the copper atom in a CuSO4 molecule is +2.

Properties of CuSO4-Cupric Sulfate
The physical and chemical properties of copper sulfate are discussed in this subsection.
Cupric Sulfate can be noted that the properties of anhydrous CuSO4 and CuSO4.5H2O vary considerably, and have been highlighted separately.

Physical Properties
The molar mass of the anhydrous and the pentahydrate forms of copper sulfate are 159.609 grams/mole and 249.685 grams per mole respectively.
Anhydrous Cupric Sulfate has a grey-white, powdery appearance whereas the pentahydrate has a bright blue colour.
The densities of the anhydrous and pentahydrate forms are 3.6 grams per cubic centimetre and 2.286 g.cm-3
Both hydrated and anhydrous copper sulfates tend to decompose on heating and hence do not have exact boiling points.
Anhydrous Cupric Sulfate has an orthorhombic crystal structure whereas CuSO4.5H2O crystals have triclinic structures.

Chemical Properties
The copper ions present in copper sulfate react with the chloride ions belonging to concentrated hydrochloric acid, leading to the formation of tetrachlorocuprate(II).
The chemical equation for this reaction is given by Cu2+ + 4Cl– → CuCl42-
When heated to 650oC, CuSO4 undergoes a decomposition reaction to yield cupric oxide (CuO) and SO3 (sulfur trioxide).
Cupric Sulfate is highly soluble in water, with solubility values of 1.055 molal and 1.502 molal ate 10oC and 30oC respectively.
A typical example of a single displacement reaction where one metal displaces another is the reaction between iron and copper sulfate, given by the reaction Fe + CuSO4 → FeSO4 + Cu
