Balance the reaction of KMnO4 + H2SO4 + (NH4)2C2O4 = MnSO4 + CO2 + K2SO4 + (NH4)2SO4 + H2O using this chemical equation balancer!
4K+(aq) + 4MnO4-(aq) + 12H+(aq) + 6SO42-(aq) = 4K+(aq) + 2SO42-(aq) + 4Mn2+(aq) + 4SO42-(aq) + 6H2O(l) + 5O2(g) Spectator Ions Spectator ions are ions that do not take part in the reaction. They are removed from the complete ionic equation t...
acidify 即系提供酸性环境令MnO4-作为oxidizing agent的反应可以发生： MnO4- + 8H+ + 5e- => Mn2+ + 4H2O (明显这个反应需要H+才可以发生) KMnO4 可以用 dilute H2SO4 去 acidify，因为两者并无reaction，即系H2SO4真正只提供acidic medium 如果用HCl，会与MnO4- react，咁就会消耗左MnO4-，...

Actually in the system I only have: KMnO4, H2O, H2SO4. In the forum, I found: KMnO4 + H2SO4 + H20 --> KHSO4 + MnO4- + H30+ Is KHSO4 dark red? Due to color change, I assume that redox reaction took place. Thus, MnO4- --> Mn2+ (in acidic solution), which should be ...
