Iron (II) Sulphate Heptahydrate - FeSO4.7H2O - 200 g

Chemical formula: FeSO4.7H2O

Synonyms: Ferrous sulfate; green vitriol; iron vitriol; copperas

Amount: 200 g

Appearance and odour: small green crystals without appreciable odour.

Grade: 99 %

Packaging: professional wide necked, white HDPE bottle with blue conical seal cap and tamper ring. Labelled. Bottle and cap are UN approved and reusable.

Description and uses: a good source of Fe2+ (ferrous - oxidation state II) ions. This grade is highly and completely water soluble. It’s the basis of many Fe (II) salts. Oxidises easily to Fe (III), even by air. Precipitate with alkali, redissolve in acid to obtain other iron salts.

Note that this is not a common garden grade (moss killer), most of which contain anti-caking agents and show signs of partial oxidation and poor water solubility.

A mild reducing agent, common oxidisers like oxygen, nitric acid, chlorine, hydrogen peroxide and many others oxidise Fe (II) to Fe (III) and this is the basis for the production of many ferric (III) compounds.

At close to 500 Celsius in air it decomposes undergoing oxidation with sulphur dioxide and trioxide being liberated.

Dispatch: depending on time of receipt of your order, your item will be dispatched either same day or next day at the latest.
