Which one amongst the following are good oxidizing agents?
A. Sm$^{2+}$
B. Ce$^{2+}$
C. Ce$^{4+}$
D. Tb$^{4+}$
Choose the most appropriate answer from the options given below :
Solution
The most appropriate answer is $C$ and $D$ only. $Ce^{4+}$ and $Tb^{4+}$ are good oxidizing agents because they have a high oxidation state and a strong tendency to gain electrons. $Sm^{2+}$ and $Ce^{2+}$ are reducing agents because they have a low oxidation state and a tendency to lose electrons.
