The standard reduction-potential for the half-cell \( \mathrm{NO}_{3}^{-}(a q)+2 \mathrm{H}^{+}+e^{-} \longrightarrow \mathrm{NO}_{2}(g)+\mathrm{H}_{2} \mathrm{O} \) is \( 0.78 \mathrm{~V} \)
(i) Calculate the reduction-potential in \( 8 \mathrm{M} \mathrm{H}^{+} \).
(ii) What will be the reduction-potential of the half-cell in a neutral solution? Assume all the other species to be at unit concentration.
