Question

On the basis of standard electrode potential values, suggest which of the following reactions would take place? (Consult the book for E^Θ value).

$Cu + Zn^{2 +} ⟶ Cu^{2 +} + Zn$

Long Answer

Solution

Here Cu undergoes oxidation so it acts as anode and Zn acts as the cathode. So from the table

For cathode E^Θ cathode = – 0.76 V

For anode E^Θ anode = 0.52 V

E^Θ cell = – 0.24V

As the EMF of the cell is negative the given reaction will not occur spontaneously if they were to form a cell placed as electrodes.
