Description

Ammonium Ferrous Sulfate is an inorganic salt primarily known as Mohr's salt, valued for its stability and utility as a source of ferrous ions. This compound is essential in analytical chemistry as a primary standard for titrations and serves as a reliable reducing agent in various industrial processes. Key industries that utilize this material include water treatment, pharmaceuticals, and agriculture, where it functions as a nutrient and precipitating agent.

Application

• Analytical Chemistry Standard: Used as a primary standard for the calibration of potassium permanganate and cerium(IV) solutions in redox titrations.
• Water Treatment: Acts as a coagulant and reducing agent for the removal of contaminants like chromium(VI) and chlorinated organics.
• Agricultural Micronutrient: Serves as a source of bioavailable iron in fertilizer formulations to correct chlorosis in plants.
• Pharmaceutical Intermediate: Employed in the synthesis of iron-based compounds and as a reagent in quality control laboratories.
• Laboratory Reagent: A common source of Fe²⁺ ions in educational and research settings for experiments in electrochemistry and synthesis.
• Wastewater Remediation: Utilized in Fenton-like processes to catalyze the degradation of organic pollutants.
• Photography & Textiles: Historically used in developing solutions and as a mordant in dyeing processes.
