Sulphuric Acid (0.5 N), in Aqueous Solution, Analytical Reagent

The NIST traceability to SRM 723 with compliance to APHA and ASTM standards provides the highest level of standardization and analytical confidence for regulatory compliance. The high-purity acid and deionized water formulation minimizes impurities that could interfere with analytical accuracy. The normality of 0.499N - 0.501 N maintains consistent concentration for precise titration procedures. The 2-year shelf-life provides extended usability while maintaining standardized concentration and NIST-traceable performance.
