Solution: A 12-V automotive lead-acid battery. Each anode/cathode pair in this schematic cutaway produces a voltage of about 2 V. Six pairs of electrodes are connected in series, producing 12.What is the oxi

Problem

A diagram shows alternative panels of lead grids filled with spongy lead (anode) and lead grids filled with PbO2 (cathode). The panels are bathed in H2SO4 electrolyte, which is contained by the battery casing.
