TRUE or FALSE. Write TRUE if the statement is correct and FALSE if the statement is wrong. 1. Batteries can be recharged use an outside power Source to reverse electrode reactions. Those that cannot be recharged use redox reactions that cannot be easily reversed. 2. The automobile battery is the best example of a lead storage battery. 3. For lead storage battery, the anode and cathode are both immersed in the electrolyte sulfuric acid, which is commonly called battery acid. 4. The most common fuel cell is the hydrogen – oxygen fuel cell, where H2 is pumped into the anode and O2 is directed into the cathode. 5. Primary batteries are single-use batteries because they can be recharged.
