Question 8

8. An electrolytic cell is constructed using platinum electrodes in an aqueous NaHCO3 solution. The electrolytic cell is attached to a 9V battery for 2.5 hours, producing 55 mL of H2(g) at 1.00 atm and 298 K. 2HCO3(aq) + 2e- → H2(g) + 2CO3²-(aq) E° = -0.83 V O2(g) + 4CO2(g) + 2H20 (1) + 4e →→ 4HCO3(aq) E° = 2.73 V a. Identify the anode reaction, cathode reaction, and cell reaction. Anode: Cathode: Cell: b. Calculate the current running through the cell. C. Calculate the total volume of gas produced during the electrolysis. Answer: Answer:
