Expalin the following:
The $E^{o} c u^{21} / c u$ for copper metal is positive $(+ 0.34)$ , unlike the remaining members of the first transition series

Solution

$E^{\circ} (M^{2 + / M})$ value of a metal depends on the energy changes involved in the following:
(1) Sublimation
$M_{(s)} \to M_{g}$
(2) Ionization
$M_{g}^{2} \to M_{g}^{2 +}$
(3) Hydration
$M_{(g)}^{2} \to M^{2 +} (a q)$
As copper has a high energy of atomization and low hydration energy. Hence, the $E^{\circ} (M^{2 +} / M)$ value of copper is positive.
