Application

Ammonium iron(ii)sulfate serves a crucial role in analytical chemistry, particularly as an analytical reagent in titrations and colorimetric measurements. Its primary purpose is to measure oxidizing substances, such as chlorine, and to assess the chemical oxygen demand in wastewater. This compound is essential for preparing a Fe(II) standard solution, which is fundamental in these analyses. Furthermore, ammonium iron(ii)sulfate acts as a calibration standard in magnetic measurements, functions as a reducing agent, serves as a catalyst for polymerization processes, and finds use in photographic chemistry. With a composition that includes ammonium, iron, and sulfate ions in a 2:1:2 ratio, the compound is characterized by its pale green or blue-green color, appearing either as a powder or as lumpy crystals, and possesses a molecular weight of 392.14. It is soluble in water and, based on the NFPA-704 M Rating System, has a health hazard rating of 3, no flammability risk, and a reactivity rating of 1.
