DUAN Qun-zhang (Central South University of Technology,Changsha 410083)  
In aqueous solutions, chemical property of cation or oxideacid anion of all same elements was great difference because difference valence condition. The more valence conditions were stronger, the more its oxidizing ability was stronger. In this article, the influence of ion valence condition in aqueous solution on its chemical property, and how to use ion valence condition in chemical analysis were discussed.
