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 insoluble silver thiocyanate. Employed in quality control laboratories for assaying pharmaceuticals, ores, and industrial chemicals. Also utilized in calibration of instruments and validation of analytical methods requiring precise concentration of thiocyanate ions. Suitable for use in environmental testing to measure halide impurities and in educational labs for teaching titration techniques.
