Final answer:

In the given reaction, Cl is the substance that is reduced and acts as the oxidizing agent. It is a redox reaction.

Step-by-step explanation:

In the reaction 2H2O (l) + 2Cl– (aq) → H2 (g) + Cl2 (g) + 2OH– (aq), the substance that is reduced is Cl. The Cl2 is being reduced and is the oxidizing agent. The reaction involves a transfer of electrons, making it a redox reaction.

A. H2O is the substance reduced.

H2O + 2e^(-) →H_2 + 2OH^(-)

The substance that gains electrons is reduced.

Remember OIL RIG (Reduction Is Gain of electrons) and

LEO the lion says GER (Gain of Electrons is Reduction).
