Consider the following standard electrode potentials (E° in volts) in aqueous solution :
Based on these data, which of the following statements is correct ?
| Element | $\displaystyle \mathbf{M}^{\mathbf{3} \boldsymbol{+}} \boldsymbol{/} \mathbf{M}$ | $\displaystyle \mathbf{M}^{+} \boldsymbol{/} \mathbf{M}$ |
| Al | -$\displaystyle 1.66$ | + $\displaystyle 0.55$ |
| Tl | +$\displaystyle 1.26$ | - $\displaystyle 0.34$ |
Official answer
(3)
$\displaystyle \mathrm{Tl}^{+}$is more stable than $\displaystyle \mathrm{Al}^{+}$
