Ammonium Ferrous Sulphate CP

CP grade ammonium ferrous sulphate is supplied for industrial and educational laboratory use.

Ammonium Ferrous Sulphate CP

(Chemically Pure) refers to a laboratory-grade double salt, commonly known as Mohr’s Salt. The “CP” designation indicates a grade of purity suitable for general laboratory applications and commercial use, though it is slightly less refined than Analytical Reagent (AR) grade. 

Core Properties 
Appearance: Light green or blue-green crystalline solid.
Molecular Weight: 392.14 g/mol (hexahydrate form).
Stability: It is preferred in analytical chemistry over ferrous sulphate because it is more stable and resistant to air oxidation.
Solubility: Highly soluble in water; insoluble in ethanol. 

Common Uses 
Analytical Chemistry: Primarily used as a standard reducing agent in redox titrations (e.g., standardising potassium permanganate).
Water Purification: Employed in some water treatment processes.
Photography & Metallurgy: Used in photographic developing and iron-plating baths.
Education: A staple in school and university chemistry labs for teaching qualitative and quantitative analysis. 

Safety & Handling 
Storage: Store in a cool, dry place. It is air and light sensitive, so containers should be kept tightly closed, often under an inert gas for long-term stability.
Hazards: Generally considered a non-hazardous substance under standard regulations (EC 1272/2008), but may cause mild skin/eye irritation or nausea if ingested in large quantities.
Incompatibilities: Keep away from strong acids and strong oxidizing agents to prevent hazardous decomposition into nitrogen and sulphur oxides.
