Abstract The oxidation of oxalic acid by the potassium tetrabromoaurate(III) in 0.005≤ [H2C2O4]≤0.07 mol dm-3 is studied by UV spectrophotometry in the temperature range of 293.2 – 313.2 K. Under pseudo-first-order conditions ([H2C2O4]0 ≥10[Au(III)]0), it is first order in [Au(III)] and [H2C2O4]. Both H+and Br– retard the reaction. The reactive species for Au(III) is AuBr3(H2O). A mechanism for this reaction […]

Abstract The kinetics and mechanism of ruthenium(III) catalyzed oxidation of isobutyl alcohol(IBA) by cerium(IV) in sulfuric acid media has been investigated by titrimetric technique of redox in the temperature range of 298-313K. It is found that the reaction is first-order with respect to Ce(IV) and Ru(III), and a positive fractional order with respect to IBA. It […]
