| Abstract: | The oxidation of dimethylhydrazine hydrazine and hydroxylamine by 12-tungsto-balt (III) ate in acetate buffer solution were investigaied.In the pH range of the experiment,all the systems have a similar empirical rate equation:The values of the activation parameters of the reactions were given.A mechanism of electron transfer through hydrogen bonding was suggested. |
