Which best describes the reducing agent in the reaction below?
Cl2(aq) + 2Br–(aq) Right arrow. 2Cl–(aq) + Br2(aq)
Bromine (Br) loses an electron, so it is the reducing agent.
Bromine (Br) gains an electron, so it is the reducing agent.
Chlorine (Cl) loses an electron, so it is the reducing agent.
Chlorine (Cl) gains an electron, so it is the reducing agent.
