Iron sulphate

 

Sulfate iron(II), iron(II) sulfate is the inorganic compound, iron salt of sulfuric acid with the formula FeSO4. Non-volatile, odorless. The anhydrous substance is a colourless, transparent, very hygroscopic. Crystalline — hygroscopic crystal transparent bright bluish-green tetrahydrate is FeSO4·4H2O green (rosenet), the monohydrate, FeSO4·H2O colorless (smolniki). The taste is strongly astringent ferrous (metal). The air gradually wear off (lose crystallization water).

The iron sulfate(II) it is soluble in water (26.3 g at 20 °C). From aqueous solutions kristallizuetsya bluish-green heptahydrate FeSO4·7H2O, which is a common name vitriol. Toxicity iron sulphate is relatively low.

Used in the textile industry, in agriculture as fungicide, for making mineral paints.

Natural analogue — mineral melanterite; in nature it occurs in crystals of the monoclinic system, green-yellow, in the form of adhesions or incrustations.

Sulfate bivalent iron stands out at temperatures from 1,82 °C to 56,8 °C from aqueous solutions in the form of light green crystals of crystalline FeSO4·7H2O, which is called in the technique of iron sulphate. In 100 g of water dissolve 26,6 g of anhydrous FeSO4 at 20 °C and 54.4 g at 56 °C.

The sulphate solutions iron(II) under the action of the oxygen of the air gradually oxidize, turning into ferric sulfate(III).

When heated more than 480 °C iron sulfate is decomposed.

Iron sulfate can be prepared by action of dilute sulphuric acid on scrap iron, trimming roofing iron, etc. In industry it is obtained as by-product in the pickling of iron sheets, wire, remove, scale , etc. of dilute H2SO4.

Another method — oxidative roasting of pyrite.

In the industry produced as a by-product of the production of titanium oxide from ilmenite.

Used in the manufacture of ink, in dyeing (for dyeing wool in black color), for preserving wood.

In medicine used as a medicament for the treatment and prevention of iron-deficiency anemia.

Used in ferrosulfate method, chemical dosimetry.

In rural the farm used for spraying orchard trees.

Iron sulfate used for pest control of gardens and slugs, to destroy moss, lichens and fungal spores and also for plant nutrition and salinity control soil; it is also used in the textile industry, for cooking ink and mineral paints, for wood preservation, as a reagent in chemical laboratories, etc.

Waste solutions sulphate of iron is processed in the insulating material — Ferron or perigees, which is a mixture of hydrates of iron oxides and gypsum with filler.

When working with iron sulphate in the room odor; besides, if work with it with bare hands, in contact with a cut on the skin can cause pain.
