Ferric Salts are used in many different municipal and industrial applications. In water and wastewater treatment operations, ferric salts are used as coagulants or flocculants for water clarification, odour control to minimize hydrogen sulfide release, for phosphorus removal, and as a sludge thickening, conditioning and dewatering agent.
Liquid Ferric Sulphate is a red-brown aqueous solution that is typically sold as a 50% or 60% strength solution, on a dry basis. Based on ferric iron (Fe+3) contents of 10% and 12% respectively for the two concentrations of liquid ferric sulphate, the formula for dry ferric sulphate would be Fe2(SO4)3•8.8H2O. The maximum concentration of ferric iron is approximately 13% in commercial liquid products.
Iron(III) Sulphate, also called ferric Sulphate, is an industrial scale commodity chemical compound, with the formula Fe2(SO4)3 and with iron in the +3 oxidation state. The colour of iron(III) sulphate crystals depends on the viewing angle: by reflected light, the crystals appear dark green, but by the transmitted light they appear purple-red. Anhydrous iron(III) sulphate is deliquescent, forming hydrated hydrogen chloride mists in moist air. It is rarely observed in its natural form, the mineral molysite, known mainly from some fumaroles.

Ferric Sulphate Other Uses
- Used in anhydrous form as a drying reagent in certain reactions.
- Used to detect the presence of phenol compounds in organic synthesis; e.g., examining purity of synthesised Aspirin.
- Used in water and wastewater treatment to precipitate phosphate as iron(III) phosphate.
- Used by American coin collectors to identify the dates of Buffalo nickels that are so badly worn that the date is no longer visible.
- Used by bladesmiths and artisans in pattern welding to etch the metal, giving it a contrasting effect, to view metal layering or imperfections.
- Used to etch the widmanstatten pattern in iron meteorites.
- Necessary for the etching of photogravure plates for printing photographic and fine art images in intaglio and for etching rotogravure cylinders used in the printing industry.
- Used to make printed circuit boards (PCBs).
- Used in veterinary practice to treat overcropping of an animal’s claws, particularly when the overcropping results in bleeding.
- Reacts with cyclopentadienylmagnesium bromide in one preparation of ferrocene, a metal-sandwich complex.
- Sometimes used in a technique of Raku ware firing, the iron colouring a pottery piece shades of pink, brown, and orange.
- Used to test the pitting and crevice corrosion resistance of stainless steels and other alloys.
- Used in conjunction with NaI in acetonitrile to mildly reduce organic azides to primary amines.
- Used in an animal thrombosis model.
- Used in energy storage systems
- Historically it was used to make direct positive blueprints.
- A component of modified Carnoy’s solution used for surgical treatment of keratocystic odontogenic tumour (KOT)

What is the use of flocculant?
Iron(III) Sulphate is harmful, highly corrosive and acidic. The anhydrous material is a powerful dehydrating agent.
Although reports of poisoning in humans are rare, ingestion of ferric sulphate can result in serious morbidity and mortality. Inappropriate labelling and storage lead to accidental swallowing or misdiagnosis. Early diagnosis is important, especially in seriously poisoned patients.
