Consider the electrochemical cell :$Zn (s) / Zn^{2+} (aq) // Cu^{2+} (aq) / Cu.$ It has an electrical potential of 1.1 V when concentration of $Zn^{2+}$ and $Cu^{2+}$ ions is unity.State the direction of flow of electrones and also specify if Zinc and Copper aredeposited or dissolved at their respective electrodes. When :(a) an external opposite potential of 0.8 V is applied.(b) an external opposite potential of 1.1 V is applied.(c) an external opposite potential of 1.4 V is applied.
