在硝酸介质中PbO_2氧化Mn^(2+)的产物

The products as PbO_2 oxides mn^(2+) in the medium of nitric acid

研究了在硝酸介质中，Ｍｎ２＋被ＰｂＯ２氧化的产物。实验结果表明：氧化产物与ＰｂＯ２的用量和Ｍｎ２＋的浓度有关；在Ｍｎ２＋浓度较低时，反应产物与硝酸的浓度无关。

It's studied in this article the products when Mn2+ was oxiden by PbO2 the experiment shows: Oxide relates to the quantity of PbO2 and the concentrations of Mn2+, doesn' t relate to the concentrations of HNO3.
