What Is Ammonium Ferric Sulphate?
Chemically, Ammonium Ferric Sulphate has the formula FeNH₄(SO₄)₂·12H₂O. It is a violet or light purple crystalline solid that dissolves easily in water to produce an acidic solution. The compound belongs to the alum family, which consists of double sulfates of monovalent and trivalent metals.
- Chemical formula: FeNH₄(SO₄)₂·12H₂O
- Molecular weight: 482.19 g/mol
- Appearance: Violet to light purple crystals
- Solubility: Soluble in water, insoluble in alcohol
- pH (1% solution): Approximately 2.0
Due to its stability and well-defined composition, Ammonium Ferric Sulphate is a dependable oxidizing agent and analytical standard in many scientific and industrial settings.
Applications of Ammonium Ferric Sulphate
1. Analytical Chemistry
Ammonium Ferric Sulphate is widely used as a standard oxidizing agent in redox titrations, particularly in cerimetric and dichromate titrations. It provides consistent results because of its well-defined stoichiometry and stable crystalline form. Laboratories use it to determine reducing agents and to standardize solutions of potassium permanganate.
At Reflecta Laboratory Supplies, our analytical-grade Ammonium Ferric Sulphate is ideal for laboratories that require precision and reliability in volumetric and quantitative analysis.
2. Water Treatment and Environmental Testing
In water treatment and environmental testing, Ammonium Ferric Sulphate functions as a coagulant to remove impurities, suspended particles, and color from water. Its ability to neutralize negatively charged particles helps in clarifying both drinking water and industrial wastewater.
Reflecta Laboratory Supplies supports environmental laboratories and water treatment facilities with high-purity Ammonium Ferric Sulphate that meets the performance requirements for these critical applications.
3. Industrial Applications
Industrially, Ammonium Ferric Sulphate is used in the dyeing, textile, and leather industries as a mordant — a chemical that helps fix dyes to fabrics or hides. It also plays a role in the manufacturing of pigments and in certain photographic and electrochemical processes where controlled oxidation is required.
4. Educational and Research Laboratories
In teaching laboratories, Ammonium Ferric Sulphate is a common compound for demonstrating redox reactions, iron chemistry, and the properties of alums. Its vivid color and safe handling profile make it an ideal reagent for academic settings.
Handling and Storage Guidelines
Ammonium Ferric Sulphate should be handled using standard laboratory safety practices. It may cause mild irritation upon contact with skin or eyes and should be used in a well-ventilated area.
Storage recommendations:
