MCQ
Which of the following solution is strongest oxidizing agent?
- A$\text{MnO}_4^- $ in acidic medium.
- B$\text{MnO}_4^-$ in basic medium.
- C$\text{MnO}_2$ in basic medium.
- D$\text{CrO2}_4^-$ in basic medium.
Explanation:
$\text{MnO}_4^-+3\text{e}^-+2\text{H}_2\text{O}\xrightarrow{ \ \ \ \ \ \ \ \ }\text{MnO}_2+4\text{OH}^-$
E° = 1.69V, which is highest.
