Question 1

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

ClO-(aq) + Cr(OH)4-(aq) → CrO42-(aq) + Cl-(aq)


◦ Cr(OH)4-(aq) + 4 OH-(aq) → CrO42-(aq) + 4 H2O(l) + 3e-
◦ ClO-(aq) + 2 H+(aq) + 2e- → Cl-(aq) + H2O(l)
◦ Cr(OH)4-(aq) → CrO42-(aq) + 4 H+(aq) + 3e-
◦ ClO-(aq) + H2O(l) + 2e- → Cl-(aq) + 2 OH-(aq)

Question 2

According to the balanced equation shown below, 1.00 mole of oxalic acid, H2C2O4, reacts with ________ moles of permanganate ion, MnO4-.

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


◦ 2.00
◦ 0.400
◦ 1.00
