A cell is constructed as follows:
Zn|0.1M ZnSO4 ||0.1M KMnO4,0.01M Mn2+,[H+]=1.0M|Pt
Write the balanced cell reaction?
阳极：Zn-->ZnSO4 +2e-
阴极：KMnO4 +5e--> Mn2+
balanced reaction:5Zn+2KMnO4-->5ZnSO4+2Mn2+ ????是这样吗～～～

wish..与现实相反的假设语气..

1F：推 yiso:阳极 Zn →Zn2+ + 2e- 59.115.231.172 06/26 20:03
2F：→ yiso:阴极 MnO4- + 8H+ + 5e-→ Mn2+ + 4H2O 59.115.231.172 06/26 20:04
3F：→ yiso:两式再相加 就是净反应式了 59.115.231.172 06/26 20:04
4F：→ yiso:旁观离子不写没关系 59.115.231.172 06/26 20:05
5F：→ jayjet:了解..感谢啦～～220.135.113.220 06/27 18:57
