◦ 4
◦ 5
◦ 7
◦ 2

Question 2

What is the oxidation half reaction in the following chemical reaction?

Cr2O72-(aq) + 6 Cl-(aq) + 14 H+(aq) → 2 Cr3+(aq) + 3 Cl2(aq) + 7 H2O(l)


◦ Cl2(aq) + 2e- → 2 Cl-(aq)
◦ 2 Cl-(aq) → Cl2(aq) + 2e-
◦ Cr2O72-(aq) + 14 H+(aq) + 6e- → 2 Cr3+(aq) + 7 H2O(l)
◦ Cr2O72-(aq) + 14 H+(aq) → 2 Cr3+(aq) + 7 H2O(l) + 6e-
