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?
陽極：Zn-->ZnSO4 +2e-
陰極：KMnO4 +5e--> Mn2+
balanced reaction:5Zn+2KMnO4-->5ZnSO4+2Mn2+ ????是這樣嗎～～～

wish..與現實相反的假設語氣..

推 yiso:陽極 Zn →Zn2+ + 2e- 59.115.231.172 06/26 20:03
→ yiso:陰極 MnO4- + 8H+ + 5e-→ Mn2+ + 4H2O 59.115.231.172 06/26 20:04
→ yiso:兩式再相加 就是淨反應式了 59.115.231.172 06/26 20:04
→ yiso:旁觀離子不寫沒關係 59.115.231.172 06/26 20:05
