Used in volumetric analysis to determine the concentration of silver ions in samples through titration, particularly in the Volhard method. It serves as a secondary titrant where excess silver nitrate is added to a sample, and the unreacted silver ions are back-titrated with this solution. Commonly applied in the analysis of halides in water, pharmaceuticals, and industrial chemicals. Also utilized in quality control laboratories for standardization of silver nitrate solutions and in environmental testing to measure chloride and bromide levels. Its precise concentration ensures accurate and reproducible analytical results.
