To arrange the species \( \text{MnO}_4^{-} \), \( \text{Cr}_2\text{O}_7^{2-} \), and \( \text{VO}^{2+} \) in increasing order of their oxidizing power, we will analyze the reduction reactions and the stability of the reduced forms of these species. ### Step 1: Identify the reduction reactions - **For \( \text{VO}^{2+} \)**: It is reduced to \( \text{V}^{3+} \). - **For \( \text{MnO}_4^{-} \)**: It is reduced to \( \text{Mn}^{2+} \). - **For \( \text{Cr}_2\text{O}_7^{2-} \)**: It is reduced to \( \text{Cr}^{3+} \). ### Step 2: Determine the oxidation states ...
