Given below are two statements:
Statement $\mathrm{I}: \mathrm{CeO}_{2}$ can be used for oxidation of aldehydes and ketones.
Statement II : Aqueous solution of $\mathrm{EuSO}_{4}$ is a strong reducing agent.
In the light of the above statements, choose the correct answer from the options given below:
Correct Option: , 3
The $+3$ oxidation state of lanthanide is most stable and therefore lanthanide in $+4$ oxidation state has strong tendence to gain $\mathrm{e}^{-}$and converted into $+3$ and therefore act as strong oxidizing agent.
eg $\mathrm{Ce}^{+4}$
And there fore $\mathrm{CeO}_{2}$ is used to oxidized alcohol aldehyde and ketones.
Lanthanide in $+2$ oxidation state has strong tendency to loss $\mathrm{e}^{-}$and converted into $+3$ oxidation state therefore act as strong reducing agent.
$\therefore \mathrm{EuSO}_{4}$ act as strong reducing agent.
