Which Best Describes The Oxidizing Agent In This Reaction? Cl2(Aq) + 2Br–(Aq) Right Arrow. 2Cl–(Aq) + Br2(Aq) Bromine (Br) Is The Oxidizing Agent Because It Gains An Electron. Bromine (Br) Is The Oxidizing Agent Because It Loses An Electron. Chlorine (Cl) Is The Oxidizing Agent Because It Gains An Electron. Chlorine (Cl) Is The Oxidizing Agent Because It Loses An Electron.. In a redox reaction, the oxidizing agent is the substance that is reduced (gains electrons), while the reducing agent is the substance that is oxidized (loses electrons). The oxidizing agent, or oxidant/oxidizer, is a species that oxidizes other substances and gains electrons (i.e.
