6. The following Pourbiax diagram is for the lead metal +10 +0.75 +0.5 +0.25 E(V) 0 -0.25 -0.5 -0.75 -1.0 Pb2+ Pb 1 A. Is PbO2 a better oxidizing agent at pH-5 or pH=11? B. Is Pb a better reducing agent at pH= 0 or pH=14? 7 PH C. What is the approximate redox potential of Pb+2 at pH= 3? PbO₂ a. Pb(OH)2 9 11 14 [20 points] D. What reaction occurs across the line labeled "a" at pH=9 in the lead Pourbaix diagram? Write a balanced equation. E. Increasing the temperature will shift the line between Pb and Pb²+ to more noble or less noble potentials? Explain your answer. 6.
