Lead-Acid Batteries Traditional car batteries (not those in EVs) are lead-acid batteries. This diagram shows the construction of a modern lead-acid battery and the overall cell reaction. + electrode electrode cathode (+): lead grid filled with PbO2 anode (-): lead grid filled with spongy lead electrolyte: solution of sulfuric acid cell reaction: Pb(s) + PbOz(s) + 2 SO42-(aq) + 4 H*(aq) 2 PbSO4(s) + 2 H20(1) 1. Based on the cell reaction provided, identify and write out the two half-reactions as reduction half-reactions. Also, look up and report the standard reduction potentials for these half-reactions (found in Appendix L in the textbook). 2. Write a cell line notation describing this galvanic cell. Make sure that you clearly identify the electrode material in each of the half-cells
