Zinc sulphate Chemical Properties,Uses,Production

Description

Zinc sulfate appears as colorless or white rhombic crystals or powder at room temperature. It has convergence property and is easily soluble in water with its aqueous solution being acidic. It is slightly soluble in ethanol and glycerol. Pure zinc sulfate can be stored in the air for a long time without turning yellow. It can lose water to become white powder when placed in dry air. There are various kinds of hydrates: in the range of 0-39 ° C, its stable hydrate balanced with aqueous phase is zinc sulfate heptahydrate; in the range of 39-60 ° C, it is hexahydrate zinc sulfate. At the range of 60-100 °C, it will become zinc sulfate monohydrate. When being heated to 280 °C, various kinds of hydrate will completely lose water with decomposition into zinc sulfate at 680 °C and further decomposition at above 750 ° C and finally decomposition into zinc oxide and sulfur trioxide at about 930 °C. ZnSO4 • 7H2O can form mixed crystal with MSO4 • 7H2O (M = Mg, Fe, Mn, Co, Ni) within a certain range. It is mainly used for the preparation of raw materials of pigment lithopone, zinc barium and other zinc compounds. It also has various kinds of applications such as animal nutrition upon zinc deficiency, animal feed additives, crop zinc fertilizer (trace element fertilizer), important materials of artificial fiber, electrolyte solution upon electrolytic production of zinc metal, mordant in the textile industry, pharmaceutical emetic agents, astringents, fungicides and wood and leather preservatives. It can be derived from the reaction between zinc or zinc oxide and sulfuric acid or from the baking of sphalerite in the baking furnace followed by extraction and refining.

Uses

Zinc sulfate occurs in nature as the mineral, zinkosite. The heptahydrate, ZnSO4•7H2O is the mineral, goslarite. The salt is used as a mordant in calico-printing, in making rayon, in preserving wood, in animal feeds, in electroplating, and in preparing many zinc compounds.

Indications

Production Methods

Zinc sulfate is produced as an intermediate in recovering zinc from mineral zinc blende, ZnS (see Zinc, Recovery). The mineral is roasted at about 1,000°C to form zinc oxide and sulfur dioxide which, on prolonged heating in excess air, converts to zinc sulfate:
2ZnS + 3O2 → 2ZnO + 2SO2
992 ZINC SULFATE2ZnO + 2SO2 + O2 → 2ZnSO4
In the zinc recovery process, roasted products are leached with sulfuric acid, whereupon zinc oxide is converted to sulfate.
ZnO + H2SO4 → ZnSO4 + H2O
Also, zinc sulfate can be prepared by reacting metallic zinc with dilute sulfuric acid followed by evaporation and crystallization:
Zn + H2SO4 → ZnSO4 + H2

Definition

ChEBI: A metal sulfate compound having zinc(2+) as the counterion.

General Description

Anhydrous Zinc sulphate is a colorless crystalline solid. Zinc sulphate is also obtained as a hexahydrate, ZnSO4.6H2O, and as a heptahydrate ZnSO4.7H2O. All forms are soluble in water. All are noncombustible. The primary hazard is the threat posed to the environment. Immediate steps should be taken to limit its spread to the environment. Zinc sulphate is used in the production of rayon, as a feed supplement, and as a fertilizer ingredient.

Air & Water Reactions

Water soluble. Efflorescent in air. Aqueous solutions are acidic.

Reactivity Profile

Acidic salts, such as Zinc sulphate, are generally soluble in water. The resulting solutions contain moderate concentrations of hydrogen ions and have pH's of less than 7.0. They react as acids to neutralize bases. These neutralizations generate heat, but less or far less than is generated by neutralization of inorganic acids, inorganic oxoacids, and carboxylic acid. They usually do not react as either oxidizing agents or reducing agents but such behavior is not impossible. Many of these compounds catalyze organic reactions.

Health Hazard

Inhalation of dust causes irritation of nose and throat. Ingestion can cause irritation or corrosion of the alimentary tract. Contact with eyes or skin causes irritation.
