Final answer:
The electrolyte in an automotive lead acid battery is diluted sulfuric acid, which consists of an approximately 37% solution of sulfuric acid in water. This solution enables the chemical reactions necessary for the battery's operation. Therefore, the answer is diluted sulfuric acid.
Explanation:
The Electrolyte in an Automotive Lead Acid Battery
The electrolyte in an automotive lead acid battery is diluted sulfuric acid. Lead acid batteries are commonly used in vehicles to store and supply electrical energy. The electrolyte typically consists of an approximately 37% solution of sulfuric acid (H₂SO₄) in water, which facilitates the chemical reactions that occur during battery operation.
In the context of the battery, the sulfuric acid serves as a medium through which ions can move between the anode and cathode, allowing for the generation of electrical energy. When the battery is charged or discharged, chemical reactions involving lead (Pb) and lead dioxide (PbO₂) occur in conjunction with the sulfuric acid, producing lead sulfate (PbSO₄) and releasing energy.
Conclusion
So, the correct answer to your question regarding the electrolyte in an automotive lead acid battery is diluted sulfuric acid.
