E^\circ

values of some redox couples are given below on the basis of these values. Choose the correct option

E^\circ

values:

\begin{array}{l} B{r_2}\mathrm{/}B{r^ - } = + 1.90\\ A{g^ + }\mathrm{/}Ag(s) = + 0.80\\ C{u^{2 + }}\mathrm{/}Cu(s) = + 0.34\\ {I_2}(s)\mathrm{/}{I^ - } = + 0.54 \end{array}

View answer and explanation

Correct option: D

Cu

will reduce

B{r_2}

Option D (

Cu

will reduce

B{r_2}

) is correct because copper has a lower reduction potential than bromine, meaning it can be oxidized (act as a reducing agent) to reduce bromine.
