STUDY OF CHEMICAL OSCILLATION IN A MIXED SUBSTRATE SYSTEM OF GALLIC ACID AND ACETONE USING CERIUM(IV) IONS AS CATALYST AND A COMPARATIVE-STUDY OF THE CATALYTIC ACTIVITY OF CERIUM(IV) IONS AND FERROIN

Chemical oscillation has been studied using gallic acid and varying am ounts of acetone as the mixed organic substrate both visually and pote ntiometrically side by side by the batch method. Ce-IV ions have been used as catalyst and sulphuric acid as the medium. The results have be en compared with those obtained earlier in perchloric acid and sulphur ic acid media using ferroin as catalyst. Studies have also been made t o judge the relative efficiency of ferroin and Ce-IV ions as catalyst with single and mixed organic substrate.
