Iodide ions in aqueous solution are oxidized by atomic hydrogen produced in an electrodeless high frequency discharge and introduced into the solution. The influence of hydrogen ion and iodide ion concentration on the reaction was investigated in the pH range of 0.4-7.0. Various possible mechanisms are discussed and it is shown that of these only the mechanism involving the H+2aq ion as the actual oxidizing species agrees with all the results. Some rate constants are estimated.
