1.) Which of the following is the best oxidizing agent?

Standard reduction potentials (@25oC)

MnO 4 - + 8H + + 5e - Mn2+ + 4H2O Eo= +1.51 V

Fe 3+ + e - Fe2+ Eo= +0.77 V

I2 + 2e- 2 I- Eo= +0.54 V

Pb2+ + 2e- Pb Eo= +0.13 V

2.) In the electrolysis of an aqueous solution of Na2SO4 the products are H2(g) and O2(g). The net reaction is 2H2Oelectrolysis2H2(g)+O2(g). The function of the Na2SO4 is

Which of the following is the best oxidizing agent?

The net reaction is electrolysis 2H0 2H(g) + O(g). The function of the NaSO4 is to serve as an acid-base indicator to monitor OH or H* buildup at the electrodes. O to form Na(s) at the cathode. O to maintain electrical neutrality near the electrodes. O to produce S08* ions (via 2SO4 (aq) S08 (aq) + 2e)
