Based on the BrO-3--H＋-KMnO4 pH oscillation system ,the effect of changing the reaction parameters on the properties of the oscillation system was studied.Some new phenomena,such as the color oscillation of MnO(OH)＋ and the appearance of MnO2 precipitation were found.These phenomena by our modified reaction mechanism including an autocatalytic process of MnO(OH)＋ were explained,and its phase diagram on the [KMnO4]-Kf plane was drawn( see Fig.7).
