Which best describes the oxidizing agent in this reaction?

Cl2 (aq) + 2Br (aq) - - > 2Cl (aq) + Br2 (aq)

The reaction is:

Cl2 (aq) + 2Br - (aq) - - > 2Cl - (aq) + Br2 (aq)

The oxidizing agent is the one that is being reduced which is chlorine where the charge changed from neutral to - 1 while the reducing agent is the one being oxidized which is bromine where the charge change from - 1 to a neutral charge.
