The reactions that are taking place during the recharge of lead storage battery is 2 P b S O 4 + 2 H 2 O → P b ( s ) + P b O 2 + 4 H + + 2 S O 2 − 4 Was this answer helpful?
This reaction regenerates the lead, lead (IV) oxide, and sulfuric acid needed for the battery to function properly. Theoretically, a lead storage battery should last forever. In practice, the recharge is not (100%) efficient, because some of the lead (II) sulfate falls from the electrodes and collects on the bottom of the cells.
What Is a Chemical Reaction? Definition and Examples
A chemical reaction is a process in which the chemical structure of a substance changes, leading to the formation of a new substance with different properties. ... (negative-charged part). For example, you write NaCl for sodium chloride rather than ClNa. A balanced chemical equation follows conservation of mass and charge. There are …

Assemble a battery using the following redox couples: Zn2+/Zn and Fe2+/Fe V KCI A B a) which compartment is the anode. b) which compartment do the cit-ions migrate towards? c) in which compartment …
The series of chemical reactions that occurs in the electrodes are collectively known as oxidation-reduction (redox) reactions. In a battery, the cathode is known as the oxidizing agent...
Because galvanic cells can be self-contained and portable, they can be used as batteries and fuel cells. A battery (storage cell) is a galvanic cell (or a series of galvanic cells) that contains all the reactants needed to produce electricity. In contrast, a fuel cell is a galvanic cell that requires a constant external supply of one or more reactants to …
