Ammonium iron ii sulfate solution 0.1 N

Ammonium Iron(II) Sulfate Solution 0.1 N is an aqueous solution of ammonium iron(II) sulfate, commonly known as Mohr’s salt, prepared at a normality of 0.1 N. Mohr’s salt is a stable double salt of ferrous sulfate and ammonium sulfate that serves as a reliable source of iron(II) ions in analytical chemistry. The solution is pale green and is widely used as a standard reducing agent in volumetric analysis.

🏭⚗️ Synthesis
Ammonium Iron(II) Sulfate Solution 0.1 N is prepared by dissolving an accurately weighed amount of ammonium iron(II) sulfate hexahydrate in distilled water containing a small quantity of dilute sulfuric acid to prevent oxidation of iron(II) to iron(III). The solution is then diluted to the required final volume and standardized under controlled laboratory conditions.

🧪 Applications
Ammonium Iron(II) Sulfate Solution is widely used in analytical chemistry as a standard reducing agent for oxidation–reduction titrations. It is commonly applied in the standardization of potassium permanganate, potassium dichromate, and cerium(IV) solutions, as well as in pharmaceutical, environmental, and educational laboratories for quantitative chemical analysis.

⚠️ Safety
Ammonium Iron(II) Sulfate Solution may cause mild irritation to the eyes, skin, and respiratory tract upon exposure. Prolonged contact or ingestion should be avoided. Appropriate laboratory protective equipment, including gloves, safety goggles, and proper ventilation, is recommended during preparation and handling.
