description Product Description
Used as a primary standard in redox titrations, particularly in the standardization of potassium permanganate and potassium dichromate solutions. Its high purity and stability make it ideal for accurate volumetric analysis. Also employed in analytical chemistry for iron content determination and in the preparation of iron-based reagents. Commonly used in educational laboratories for teaching titration techniques due to its reliable stoichiometry and ease of handling. Additionally, it finds use in wastewater treatment as a coagulant aid and in the synthesis of other iron compounds.
