About Ammonium Ferric Sulfate
Ammonium Ferric Sulfate dodecahydrate (NH4Fe(SO4)2 · 12H2O) is a pale violet, crystalline solid that is highly soluble in water. It is a classic double salt of ammonium sulfate and ferric sulfate. Known colloquially as ferric alum or iron alum, it is highly valued for its stability and ease of handling compared to other iron(III) salts, making it a staple in both analytical chemistry and industrial processes.
In the Indian industrial landscape, this chemical finds extensive application across multiple sectors. It is primarily utilized as an indicator in argentometric titrations (specifically the Volhard method) in pharmaceutical and testing laboratories. Additionally, the textile industry in hubs like Tirupur and Surat employs it as a reliable mordant to fix dyes on natural fibers, while water treatment plants utilize its coagulating properties to clarify industrial effluents.
When procuring Ammonium Ferric Sulfate in India, buyers should specify the grade required—AR grade for analytical and laboratory testing, or Technical grade for bulk industrial applications. Since the compound is efflorescent and sensitive to light and moisture, ensuring proper packaging in airtight, light-resistant HDPE bags or fiber drums is critical. Buyers should partner with verified manufacturers who provide comprehensive Certificates of Analysis (CoA) detailing assay levels and insoluble matter limits.

Frequently Asked Questions
What is the price of Ammonium Ferric Sulfate in India?
Ammonium Ferric Sulfate prices in India vary by grade, order quantity and delivery location, and move with market conditions. To get the current price for your requirement, submit an enquiry on Chemical Dekho and receive verified quotes from suppliers and manufacturers within 24 hours.
What is the primary use of Ammonium Ferric Sulfate in analytical chemistry?
It is primarily used as an indicator in Volhard titrations for the determination of halides, where it forms a deep red complex with thiocyanate ions at the end point.
Why do the crystals sometimes look yellowish or brownish?
Pure crystals are pale violet. A yellowish or brownish tint indicates partial dehydration (efflorescence) or hydrolysis due to exposure to moisture and air.
Is Ammonium Ferric Sulfate the same as Ferric Alum?
Yes, Ferric Alum and Iron Alum are common industrial trade names for Ammonium Ferric Sulfate dodecahydrate.
What are the storage precautions for this chemical in hot Indian climates?
It should be stored in temperature-controlled warehouses below 30°C, as higher temperatures can cause the dodecahydrate crystals to lose water of crystallization or liquefy.
Can it be used in water treatment?
Yes, the technical grade acts as an effective coagulant in industrial wastewater treatment to precipitate suspended solids and organic matter.
