You are acquainted with the construction and working of a lead storage battery. Give the plausible reasons for these facts.
a. There is only a single compartment unlike other electrochemical cells which have two compartments
b. Addition of water is necessary from time to time for maintenance
Answers
Answer :
(a) In lead storage batteries it contains dilute sulfuric acid as electrolyte and positive and negative electrodes in form of several plate.
These plates are connected to each other.
There are group of plates assembled together.
Grouping of elements and keeping plates in assembled manner gives the enlarge surface area between the active material and electrolytes.
So great amount of electricity will produced and will make it more efficient.That is why only a single compartment is used.
(b)As these batteries are charged water in the electrolyte breaks down into oxygen and hydrogen.as this process takes place, the electrolyte level in battery decreases. So there is a need to add water time by time.
