In the reaction $H_{2} O_{2} + {Cl}_{2} \to 2 HCl + O_{2}$ , we analyze the role of H₂O₂ by observing changes in oxidation number. The oxidation number of oxygen in H₂O₂ is -1. In the product O₂, the oxidation number is 0. This increase in oxidation number (from -1 to 0) signifies a loss of electrons. A species that loses electrons is a reducing agent.

Final Answer: a reducing agent
