Interpretation: The electrode in a voltaic cell where reduction always occur needs to be identified.
Concept Introduction: In an electrolytic cell, a
Explanation of Solution
In oxidation, the oxidation state of the species increases, and in reduction, the oxidation state of the species decreases. There are two electrodes in an electrolyte cell that is anode and cathode. At the anode, oxidation takes place and at the cathode, reduction takes place.
Thus, reduction always occurs at the cathode of an electrolyte cell.
