Q.Standard electrode potential ( $E^\circ_{M^{2+}/M}$ ) for $Cu$ is $+0.34 \text{ V}$ , while for others in the $3d$ series, it is negative. This indicates that $Cu$ :

Does not liberate

H_2

from acids

Is a strong reducing agent

Is highly reactive

Is easily oxidized

The correct solution involves applying the fundamental concept to derive the final value step by step...
