N-BROMOBENZIMIDAZOLE AS AN OXIDIMETRIC TITRANT : POTENTIOMETRIC TITRATION OF SOME COMMON REDUCTANTS IN AQUEOUS ACETIC ACID MEDIUM

摘要

N-Bromobenzimidazole (BBI) has been used as an oxidimetric titrent in aqueous acetic acid medium. The direct potentiometric titration of common reductants such as Anthralinic acid Ascarbic acid, Betanapthol, Iodide, FeSO_4, MnSO_4, phenol, Rescorcinal, Succinic acid, semicarbizide & thiourea have been performed using N-Bromobenzimidazole (BBI). The proposed titrimetric methods using N-Bromobenzimidazole (BBI) are simple and provide better methods for determination of purity of the compounds.
