Question

The electrode potential of M²⁺/M of 3d-series elements shows positive value for :

Accepted Answer

Option C. In the electrode potential series, only copper have positive value for electrode potential because copper has lower tendency than hydrogen to form ions. So, if standard hydrogen electrode (E_Cell = 0) is connected to copper half-cell, the copper with be relatively less negative or less number of electrons.
