1. The following redox reaction was constructed at 25.0°C. Pb²+ (aq) + Mg(s) → Pb(s) + Mg² (aq) a. Write the half reaction that occurs at the cathode. b. How many electrons were transferred in this redox reaction? c. Calculate the Ecell for this reaction at 25.0°C. d. As the reaction progresses what happens to the mass of the magnesium electrode? (increase, decrease, or remain the same) Explain your answer. e. A chemistry student wanted to use iodide ions as the anion in the salt bridge. Why are iodide ions a bad choice?
