      More Details Abstract Fulltext PDF

      Studies on the bromate-pyrogallol system with sulphuric and perchloric acids are presented. The addition of acrylamide and acrylonitrile to the oscillatory system indicates the presence of free radicals. The apparent energy of activation for the overall process is 10.1± 1 and 20 ± 0.5 kcal mol-1 respectively for sulphuric and perchloric acids. The static potential measurements with different constituents together with double recording of oscillations with a platinum and Ag/AgBr indicator electrode establish that oscillations are caused by continuous change in the concentration of bromine and bromide ions.
