Abstract
(1) Kinetic studies using the peroxydisulphate ion as an oxidising agent have been reviewed.
(2) The kinetics of the reaction between potassium peroxydisulphate and potassium iodide have been studied at 25, 35, 45 and 55°C. using (a) 0.0025 N and (b) 0.025 N reactants. The progress of the reaction was followed by three different methods.
(3) The energy of activation obtained is discussed.
(4) The kinetics of the reaction between potassium peroxydisulphate and sodium thiosulphate have been studied using 0.025 N reactants at 25, 35, 45 and 55°C. and a mechanism at 55°C. investigated, using potassium peroxydisulphate labelled with sulphur-35.
