Which has a maximum oxidizing power among the following?

a

\({{\mathrm{VO}}_{2}}^{+}\)

b

\({\mathrm{Cr}}_{2}{{\mathrm{O}}_{7}}^{2-}\)

c

\({{\mathrm{MnO}}_{4}}^{-}\)

d

\({\mathrm{TiO}}_{2}\)

✓ Correct answer: c)

\({{\mathrm{MnO}}_{4}}^{-}\)

Explanation

Among the given species, MnO₄⁻ has the highest standard reduction potential (E° ≈ +1.52 V), making it the strongest oxidizing agent. Comparatively, Cr₂O₇²⁻ (E° ≈ +1.33 V), VO₂⁺ (E° ≈ +1.00 V), and TiO₂ are weaker oxidizers. Answer: MnO₄⁻.
