Which of the following statement is correct?
if $E_{C u^{2 +} | C u}^{\circ} = 0.34 V$ and $E_{S n^{2 +} | S n}^{\circ} = - 0.136 V$ , $E_{H^{+} | H_{2}}^{\circ} = - 0.0 V$
$C u^{2 +}$ ions can be reduced by $H_{2} (g)$
$S n^{2 +}$ ions can be reduced by $H_{2}$
$C u$ can be oxidized by $H^{+}$
$S n$ can be oxidized by $C u^{2 +}$
