Traditional lead-acid car batteries, still commonly used to start vehicle engines, rely on which acid as their electrolyte?

Explanation

Traditional lead-acid car batteries use sulfuric acid mixed with water as their electrolyte, which enables the chemical reactions between lead-based plates inside the battery that store and later release electrical energy needed to start a vehicle’s engine. Because the sulfuric acid inside these batteries is highly corrosive, proper handling and disposal of old or damaged car batteries is important for both safety and environmental reasons. Despite ongoing advances in battery technology, lead-acid batteries remain widely used in vehicles due to their relatively low cost and reliable performance for this specific starting application.
