Traditional 'battery' contains which of the following chemicals?

Solution (By Examveda Team)

A 'battery' (specifically, a traditional lead-acid car battery) uses a chemical reaction to produce electricity.
Sulphuric acid acts as the electrolyte in this battery.
The electrolyte allows the flow of electrical charge between the electrodes (lead and lead dioxide).
Ethylene glycol is antifreeze, used in car radiators to prevent freezing, not batteries.
Sodium bicarbonate is baking soda, commonly used as a cleaning agent or antacid.
Ethanol is a type of alcohol, sometimes used as a fuel or solvent.
So, sulphuric acid is the key chemical found in traditional batteries for conducting electricity.
