During electrolytic reduction, which one of the following acts as the reducing agent?
Last updated Jun 9, 2026
Correct Answer:
Option A —
Cathode
To understand why the cathode acts as the reducing agent, it helps to look at the definitions of reduction and how an electrolytic cell operates:
Reduction is the process of gaining electrons (remember the acronym OIL RIG: Oxidation Is Loss, Reduction Is Gain).
In an electrolytic cell, the cathode is the negatively charged electrode. Because it is connected to the negative terminal of the power source, it is packed with a high concentration of free electrons.
Positive ions (cations) in the electrolyte migrate toward the cathode, where they accept these electrons and are reduced.
Since the cathode provides the electrons necessary to reduce the chemical species, it effectively acts as the reducing agent.
Conversely, the anode is the positive electrode where oxidation takes place (loss of electrons), meaning it acts as an oxidizing agent.
