Multiple Choice

Consider the redox equation,
2VO₄^3-(aq) + SO₂(g) + 8H⁺(aq) $\rarr$ 2VO²⁺(aq) + SO₄^2-(aq) + 4H₂O(l)
Which of the following is correct?Hint: Write out the oxidation numbers for each element in the equation then compare.

A) VO₄^3-(aq) is the oxidizing agent as the oxidation number of O decreases by 3.
B) VO²⁺(aq) is the reducing agent as the oxidation number of V increases by 1, causing the oxidation number of S to increase by 1 also.
C) H⁺(aq) is the reducing agent, its oxidation number increases from 1 to 2, as it must have lost one electron.
D) VO₄^3-(aq) is the oxidizing agent, as the oxidation number of V decreases by 1, suggesting it must have accepted an electron.
E) SO₄^2-(aq) is the oxidizing agent and the product formed from the reduction of SO₂(g) .
