Q.Which of the following transitions represents an oxidation process?

VO_2^+ \rightarrow VO^{2+}

CrO_4^{2-} \rightarrow Cr_2O_7^{2-}

MnO_4^{2-} \rightarrow MnO_4^-

Fe^{3+} \rightarrow Fe^{2+}

The correct solution involves applying the fundamental concept to derive the final value step by step...
