Used in analytical chemistry for quantitative determination of manganese and related substances through titration and other volumetric methods. Serves as a standardized solution in redox and complexometric titrations involving Mn²⁺ ions. Commonly applied in quality control laboratories for calibration, metal ion analysis, and environmental monitoring. Suitable for use in water quality testing, pharmaceuticals, and industrial chemistry where precise manganese concentration measurements are required. Also utilized in educational settings for teaching analytical techniques and stoichiometry.
