Which among the following acid is used in car battery?

Correct option is D

The correct answer is (d) Sulphuric acid.
 Sulphuric acid (H2SO4) is used in car batteries as the electrolyte.
 It facilitates the chemical reaction between the lead dioxide (PbO2) and lead (Pb) plates in the battery, producing electrical energy.
 The acid allows the flow of ions, which is necessary for the generation of electricity and the proper functioning of the battery.
 Sulphuric acid in car batteries is usually diluted with water to form a liquid known as battery acid.
Important Key Points:
 Sulphuric acid acts as the electrolyte in car batteries.
 Facilitates chemical reactions between lead plates.
 Enables the flow of ions to generate electricity.
 Typically diluted with water in the battery.
 Essential for battery performance and longevity.
 Handle with care due to its corrosive nature.
Knowledge Booster:
 Acetic acid: Commonly found in vinegar, used in food preservation and cooking, but not in car batteries.
 Hydrochloric acid: Used in various industrial processes and in cleaning products, but not typically used in car batteries.
 Nitric acid: Used in the production of fertilizers and explosives, but not suitable for car batteries.
