Reaksi Redoks :
2KMnO4(aq) + 5H2C2O4(aq) + 3H2SO4(aq)→2MnSO4(aq) + 10CO2(g) + K2SO4(aq) + 8H2O(l)
Setengah reaksi oksidasi dari reaksi tersebut adalah . . . .
MnO4–(aq) + OH+(aq) + 5e → Mn2+(aq) + 4H2)(l)
MnO4–(aq) + 2H2O(aq) + 3e → MnO2 (s) + 4OH–(aq)
H2C2O4(aq) → 2CO2(g) + 2H+(aq) + 2e
CO2(g) + 2H+(aq) + 2e → H2C2O4(g)
2H2SO4(aq) → 2H2O(l) + 2SO2(g) + O2(g)

Diketahui potensial reduksi
Ca+2 (aq) + 2e- Ca(s) Eo = - 2,87 V
Mg+2(aq) + 2e- Mg(s) Eo = -2,37 V
Pb+2 (aq) + 2e- Pb(s) Eo = - 0,13 V
Ag+ (aq) + e- Ag(s) Eo = + 0,80 V
Reaksi berikut yang dapat berlansung spontan adalah…..
Ca+2 (aq) + Mg(s) --> Ca(s) + Mg+2 (aq)
Pb+2 (aq) + Mg(s) --> Pb(s) + Mg+2 (aq)
Pb+2 (aq) + Ag(s) --> Pb(s) + Ag+ (aq)
Mg+2 (aq) + Ag(s) --> Mg(s) + Ag+2 (aq)
Pb(s) + Ca+2(aq) --> Pb+2 (aq) + Ca(s)
