Used as a titrant in volumetric analysis for the determination of metal ions such as silver, lead, and mercury through precipitation titrations. Commonly applied in argentometric titrations where it reacts with silver ions to form silver thiocyanate, a white precipitate, especially in the Volhard method for halide determination. Also employed in calibration of instruments and validation of analytical methods in quality control laboratories. Suitable for use in environmental, pharmaceutical, and industrial testing where precise concentration measurements are required.
