Answer:
Cl2 acts as an oxidizing agent
Step-by-step explanation:
The balanced equation is
Cl2+NaOH⟶NaCl+NaClO3+H2O
Cl2 acts as a reactant in this chemical reaction
Cl2 receives one electron and thus reduces itself from Cl2 to 2 Cl−. This indicates that 2Cl- will oxidize some other element and hence Cl2 act as an oxidizing agent.
