Ferrous sulfate monohydrate

Chemical properties

Iron(II) sulfate hydrate, also known as ferrous sulfate hydrate, is Off-white to beige powder. Astringent odor. Mainly composed of FeSO4.H2O and contains a small amount of FeSO4.4H2O. harder to oxidize, and easier to store than crystalline ferrous sulfate. The aqueous solution is acidic and turbid, gradually producing a yellow-brown precipitate. It absorbs water into heptahydrate in humid air. Heating to 120 ℃ does not lose water. Boiling with water can be converted into alkali sulfate. Slowly soluble in cold water (26.6g/100ml, 20℃), rapidly dissolved when heated. Insoluble in ethanol. Almost insoluble in 50% sulfuric acid.

The Uses of Ferrous sulfate monohydrate

Iron(II) sulfate hydrate has been used to prepare ferrous ion solution to study the influence of iron ions on the thermal decomposition behaviour of hydroxylamine/water solutions.

Definition

ChEBI: Iron(2+) sulfate monohydrate is a hydrate that is the monohydrate form of iron(2+) sulfate. It is obtained from the heptahydrate by heating above 65℃. It is used as a source of iron in the treatment of iron-deficiency anaemia (generally in solid-dosage treatments; for liquid-dosage treatments, the heptahydrate is normally used). It has a role as a nutraceutical, an anti-anaemic agent and a reducing agent. It is a hydrate and an iron molecular entity. It contains an iron(2+) sulfate (anhydrous).

Preparation

It is obtained by drying crystallized ferrous sulfate into powder at 40℃. Heating to 45 ~ 50 ℃ when dissolved in the water of crystallization and liquefaction, while stirring and slowly evaporating the water of crystallization. The limit of dry weight loss is 35%~36%, generating a small particle state fine powder, made of powder, sealed and stored.

Agricultural Uses

Ferrous sulphate heptahydrate (FeSO4.7H2O), also known as green vitriol or copperas, contains 19% iron and is a common iron fertilizer. It is the best known ferrous salt.
