1 1 Which one of the following is a redox reaction? A) B) Carbonate, CO 3 2- Look at the oxidation numbers of the atoms. In which reaction do they change from reactants to products, and in which reaction do they stay the same. 2 Which atom is oxidized? A) Fe B) O C) C Which atom is reduced? Reduced means oxidation number is reduced (decreases). Oxidized means oxidation number increases. FofC Ex 2, p. 70

3 What is the oxidizing agent? A) FeO B) CO C) Fe D) CO 2 What is the reducing agent? The oxidizing agent is the species that takes the electrons. The reducing agent is the species that furnishes the electrons. FofC Ex 2, p. 70 4 SmartWork: Write half reactions for the electrolysis of molten sodium chloride. Best Answer Na + (l) + e - Na(l) 2Cl (l) Cl 2 (g) + 2e - SmartWork Answer Na + (l) Na(l) 2Cl (l) Cl 2 (g) By applying a voltage and electrical current to electrodes immersed in molten sodium chloride these half reactions will occur. One at each electrode. Sodium ions will be reduced
