Question
The standard reduction potential of oxygen in acidic solution is +1.23 V. What is the standard reduction potential of oxygen in basic solution?
Options
A.+0.404 V
B.−0.404 V
C.+2.056 V
D.−2.056 V
Solution
$O_{2}(g) + 4H^{+}(aq) + 4e^{-} \rightleftharpoons 2H_{2}O(l)$
$E_{\text{Basic}}^{o} = E_{\text{acidic}}^{o} - \frac{0.059}{4}.\log\frac{1}{\left( 10^{- 14} \right)^{4}} = 0.404\text{ V}$
