Current Question (ID: 21181)

Question:

$\text{Given that:}$ $E^\Theta_{\text{O}_2/\text{H}_2\text{O}} = +1.23 \text{ V}; \ E^\Theta_{\text{S}_2\text{O}_8^{2-}/\text{SO}_4^{2-}} = 2.05 \text{ V}$ $E^\Theta_{\text{Br}_2/\text{Br}^-} = +1.09 \text{ V}; \ E^\Theta_{\text{Au}^{3+}/\text{Au}} = +1.4 \text{ V}$ $\text{Which of the following is the strongest oxidizing agent?}$

Options:

1. $\text{S}_2\text{O}_8^{2-}$
2. $\text{O}_2$
3. $\text{Au}^{3+}$
4. $\text{Br}_2$

Solution:

$\text{Hint: Higher is the reduction potential value, higher will be}$ $\text{The strongest oxidizing agents are those species that oxidised other}$ $\text{and themselves gets reduced. Thus, the species having a high}$ $\text{reduction potential value is the strong oxidizing agent.}$ $\text{The } \text{S}_2\text{O}_8^{2-} \text{ has the highest reduction potential value thus, it is a}$ $\text{strongest oxidizing agent.}$ $\text{Thus, option first is the correct answer.}$
