Used in titration procedures to determine sulfate content in samples, particularly in water analysis, pharmaceuticals, and industrial quality control. It provides accurate and consistent results in precipitation titrations where sulfate ions react with barium to form insoluble barium sulfate. Commonly employed in environmental labs to measure sulfate levels in wastewater and natural waters. Also utilized in the food and beverage industry to ensure product purity and compliance with safety standards. Its standardized concentration ensures high precision in volumetric measurements.
