description Product Description
Used in analytical chemistry as a primary standard for redox titrations, particularly in the calibration of potassium permanganate and other oxidizing agents. It is also employed in the preparation of iron-containing reagents and in educational laboratories for teaching stoichiometry and titration techniques. Its high purity and stability make it suitable for precise measurements. Additionally, it finds use in water treatment processes and as a mordant in dyeing textiles to help fix colors.
