The kinetics or oxidation of metol ''N-methyl-p-aminophenol sulphate(1:2) ''by iodine dissolved in ethanol have been studied in acetic, hydrochloric, sulphuric and perchloric acids media and the oxidation reaction was found to be bimolecular. The rate of the reaction decreases with increase in the hydrogen ion concentration. The pseudo first order both with respect to metol and iodine has been found to be unity. The effects of concentration, acidity and temperature have been studied. The rate constants of the reaction (k), the pseude first order rate constants (k1), the activation parameters are also given and mechanism of the oxidation reaction has been suggested as well as.
