Ferric sulfate Chemical Properties,Usage,Production

Description

Ferric sulfate (iron sulfate) is the ferric salt of sulfate. It can be used as a mordant in dyeing and used as a coagulant for the treatment of industrial wastes. In the medical field, it can be used as an astringent and styptic. It is a kind of hemostatic agent being capable of controlling or stopping the flow of blood. It is also recommended that ferric sulfate is a good pulpotomy agent in primary teeth with good potential of substituting the formocresol. It can also be used in pigment, and in pickling baths for aluminum and steel. It is generally prepared through the reaction between ferrous sulfate, sulfuric acid and an oxidizing agent such as nitric acid.

Description

§184.1307(a) Ferric sulfate (iron(HI)sulfate, Fe2(S04)3), a yellow substance that may be prepared by oxidizing iron(II)sulfate or by treating ferric oxide or ferric hydroxide with sulfuric acid.

Chemical Properties

Yellow crystals or grayish-white powder.(1) slightly soluble in water, (2) very soluble in water. Keep well closed and protected from light. Noncombustible.

Chemical Properties

Ferric Sulfate is a grayish-white powder or yellow lumpy crystals.

Physical properties

The anhydrous salt constitutes grayish-white rhombic crystals; hygroscopic; density 3.10 g/cm3; slightly soluble in cold water; decomposes in hot water. The nonahydrate is a yellow hexagonal crystalline substance; refractive index 1.54; density 2.10 g/cm3; hardness 2.5 Mohs; decomposes at 400°C; very soluble in water.

Uses

Ferric Sulfate is a nutrient and dietary supplement that is a source of iron.

Uses

In preparation of iron alums, other iron salts and pigments; as coagulant in water purification and sewage treatment; in etching aluminum; in pickling stainless steel and copper; as mordant in textile dyeing and calico printing; in soil conditioners; as polymerization catalyst.

Definition

Ferrous sulfate,also known as ferrisulpas, green copperas, green vitriol, iron sulfate, and melanterite, is composed of blue green monoclinic crystals. It is soluble in water and is used as a mordant for dyeing wool in the textile industry. Ferrous sulfate is also used as a disinfectant and in the manufacture of ink.

Preparation

Iron(III) sulfate may be prepared by oxidation of iron(II) sulfate by hydrogen peroxide, nitric acid or any other suitable oxidizing agent. The reaction is carried out in sulfuric acid. Balanced molecular equations for the reactions with hydrogen peroxide and nitric acid are as follows:
2FeSO4 + H2SO4 + H2O2 → Fe2(SO4)3 + 2H2O
6FeSO4 + 3H2SO4 + 2HNO3 → 3Fe2(SO4)3 + 2NO + 4H2O
Even in the absence of an oxidizing agent, concentrated sulfuric acid alone can1 convert iron(II) sulfate to iron(III) sulfate: 2FeSO4 + 2H2SO4→ Fe2(SO4)3 + SO2 + 2H2O It also may be prepared by treating iron(III) oxide with sulfuric acid:
Fe2O3 + 3H2SO4 → Fe2(SO4)3 + 3H2O
.

General Description

A yellow crystalline solid or a grayish-white powder. The primary hazard is the threat to the environment. Immediate steps should be taken to limit its spread to the environment. Ferric sulfate is used for water purification, and as a soil conditioner.

Air & Water Reactions

Soluble in water. Hygroscopic in air. Forms acidic aqueous solutions.

Reactivity Profile

Ferric sulfate is acidic. Corrosive to copper, copper alloys, mild steel, and galvanized steel [USCG, 1999].

Health Hazard

Inhalation of dust irritates nose and throat. Ingestion causes irritation of mouth and stomach. Dust irritates eyes and can irritate skin on prolonged contact.

Agricultural Uses

Herbicide, Molluscicide, Agricultural product constituent: Ferric sulfate is used on forage alfalfa, almonds, nurseries and structural pest control. This material is also used in pigments, textile dyeing, water treatment, and metal pickling

Trade name

GREENMASTER AUTUMN®; MAXICROP MOSS KILLER®; VITAX MICRO GRAN®; VITAX TURF TONIC®

Safety Profile

A poison by intraperitoneal route. Mutation data reported. When heated to decomposition it emits toxic fumes of SOx and Fe-. See also SULFATES and other ferric salts.

Potential Exposure

This material is used in pigments, textile dyeing, water treatment; and metal pickling.

Shipping

UN3077 Environmentally hazardous substances, solid, n.o.s., Hazard class: 9; Labels: 9-Miscellaneous haz ardous material, Technical Name Required.

Purification Methods

Dissolve the sulfate in the minimum volume of dilute aqueousH2SO4 and allow it to evaporate at room temperature until yellowish-white crystals start to form. Do not concentrate by boiling off the H2O as basic salts will be formed. Various hydrates are formed; the common ones are the dodeca and nona hydrates which are violet in colour. The anhydrous salt is colourless and is very hygroscopic, but it dissolves in H2O slowly unless ferrous sulfate is added. [Gmelin’s, Iron (8th edn) pp 439-462 1932.]

Incompatibilities

Hydrolyzed slowly in aqueous solution. Incompatible with magnesium, aluminum. Corrosive to copper and its alloys, mild and galvanized steel. Light sensitive.

Waste Disposal

Treat with soda ash or dilute NaOH. Separate any precipitate and landfill. Flush solution to sewer.
