Question 1

What is the reduction half reaction for the following chemical reaction in a basic solution?

Ge2+(aq) + 2 ClO3-(aq) + OH-(aq) → GeO2(s) + 2 ClO2(aq) + H2O(l)


◦ Ge2+(aq) + 4 OH-(aq) → GeO2(s) + 2 H2O(l) + 2e-
◦ ClO3-(aq) + H2O(l) + e- → ClO2(aq) + 2 OH-(aq)
◦ ClO3-(aq) + 2 H+(aq) + e- → ClO2(aq) + H2O(l)
◦ Ge2+(aq) + 2 H2O(l) → GeO2(s) + 4 H+(aq) + 2e-

Question 2

According to the balanced chemical equation

5 H2C2O4(aq) + 2 MnO4-(aq) + 6 H+(aq) → 10 CO2(g) + 2 Mn2+(aq) + 8 H2O(l)
