In bаsic sоlutiоn, chlоrine reаcts with hydroxide ions аccording to the balanced equation: 3 Cl2 + 6 OH− → 5 Cl− + ClO3− + 3 H2O A student analyzes the reaction and makes four statements. Which of the statements is/are true?I. Chlorine is both oxidized and reduced in this reaction.II. The oxidation number of chlorine increases from 0 in Cl2 to +5 in ClO3−.III. Cl2 acts as both the oxidizing agent and the reducing agent.IV. OH− is the reducing agent because oxygen has an oxidation number of −2.
