Q.
Strong reducing and oxidizing agents among the following, respectively, are [2023]

1 ${Eu}^{2 +}$ and ${Ce}^{4 +}$

2 ${Ce}^{4 +}$ and ${Eu}^{2 +}$

3 ${Ce}^{4 +}$ and ${Tb}^{4 +}$

4 ${Ce}^{3 +}$ and ${Ce}^{4 +}$

Ans.
(1)

$(E_{{Ce}^{+ 4} / {Ce}^{+ 3}}^{0}) {}_{RP}= 1.74 V$

${Eu}^{+ 2}$ is a strong reducing agent converting to common oxidation state +3, where as $C e^{4 +}$ is a strong oxidising agent converting to +3-oxidation state.
