Used in calibration of ion-selective electrodes and conductivity meters for accurate measurement of chloride levels in water, wastewater, and industrial samples. Essential in environmental testing to monitor water quality and detect contamination. Employed in laboratories for titration procedures, such as argentometric titrations, where precise chloride concentration is required. Also used in pharmaceutical analysis and food industry testing to ensure compliance with chloride content standards. Provides a reliable reference in analytical chemistry for maintaining consistency and accuracy across measurements.
