Strong reducing and oxidizing agents among the following, respectively, are :
Solution
<p>Strong reducing agents are those that readily donate electrons, and strong oxidizing agents are those that readily accept electrons.</p>
<ul>
<li>$\mathrm{Ce}^{4+}$: It can accept an electron to form $\mathrm{Ce}^{3+}$, so it is a strong oxidizing agent.</li><br/>
<li>$\mathrm{Eu}^{2+}$: It can donate an electron to form $\mathrm{Eu}^{3+}$, so it is a strong reducing agent.</li>
</ul>
<p>So the correct answer is: $\mathrm{Eu}^{2+}$ and $\mathrm{Ce}^{4+}$.</p>
