| Abstract: | The kinetics of oxidation of sodium thiosulphate by potassiumbis(tellurato) cuprate(III) in an alkaline medium has been reported. The reaction is first order in S2O
3
2−
] but zero order in copper(III). Hydroxide ions are found to retard the oxidation rate. A rate expression rationalising the
kinetic data has been derived. Sodium tetrathionate has been found to be the product of oxidation. |
