Which of the following is the strongest oxidizing agent? b. Br (1) c. Zn2 (aq) d. Cu(aq) e. Ag (s) 15. Determine which of the following pairs of reactants will result in a spontaneous reaction at 298K a. I2 (s) + 2Ag(s) 2Ag(s) b. Zn(s) + 2Ag+(aq) Zn2+(aq) + Ag(s) c. 12 (s) + 2Br" (aq) 21"( (aq) + Br2 (1) d. Cu2+(aq) + 2Ag Cu(s) + 2Ag+(aq) e. 2Br" (aq) + Cu2+ (aq) 2 Cu(s) + Br2 (1) 16. You have a molten mixture of sodium bromide (NaBr) and sodium iodide (Nal). During electrolysis of the molten mixture, the anode reaction will produce: a. lodine (12) first, followed by Br2 b. Br2 first, followed by lodine (12) c. Metallic Sodium d. Both will be produced at the same time e. No significant reaction

Explanation / Answer

14. Option B, since greater the reduction potential greater the oxidizing capability

15. Option B, reduction potential of Ag is more,hence it readily oxidizes the Zn. Hence spontaneous.

16. Option A, Iodine first followed by Br2, since Br2 is good oxidizing agent and oxidizes tha I- to I2.
