摘　　要：以实验为基础,对PbO2与Mn2+的反应进行了研究,其结果表明在酸性溶液中强氧化剂PbO2氧化Mn2+的主要产物为MnO4-,反应物浓度、温度及酸度等反应条件是影响反应自发进行方向的重要因素.作者还运用化学热力学方法进行了讨论,从理论上阐明了反应趋势与酸度、温度的关系.This paper is based on a lot of experniments. It is studying the reaction of PbO2 and Mn^2＋ In this acid solute, MnO4^ - is the main production of the strong oxidizing agent PbO2 oxidize Mn^2＋. The trend of reaction density, product condition, temperature and acidity are effected. It has also discussed by the use of chemical thermodynamics method and theoretically expounded the relationship of reaction trend, acidity and temperature.
