Batteries and Hydrogen
1. The lead acid battery used in cars uses the reaction of Pb + PbO2 + 2H+ + 2HSO4- ---> 2PbSO4 + 2H2O and has a cell potential of 2.046 volts. How are 6 volt and 12 volt batteries produced for cars? a. The pH is made very acidic. b. 3 or 6 cells are connected together to increase the voltage c. The concentrati
