Given a galvanic cell where one of the operating half reaction is: Pb (s) + 3 OH–(aq) ––––> HPbO2–(aq) + H2O (l) + 2 e– A) State a reasonable material to be used for the electrode. B) Draw the half cell in detail and show the electrochemistry that is taking place including the electron flow. C) Identify the change in mass, if any, at the electrode. Explain any changes in mass or why there is no change in electrode mass. answer: A) Pb(s), C) Pb loses mass
