The correct answer is C. Sulphuric acid.
Sulphuric acid is a strong acid that is used in many different types of batteries, including lead-acid batteries, nickel-cadmium batteries, and lithium-ion batteries. It is a good conductor of electricity and helps to create a chemical reaction that produces electricity.
Hydrochloric acid is a strong acid that is used in some types of batteries, but it is not as common as sulphuric acid. Hydrofluoric acid is a very strong acid that is not used in batteries because it is too dangerous. Sulphurous acid is a weak acid that is not used in batteries because it is not strong enough to
produce electricity.Sulphuric acid is a colorless, odorless liquid that is highly corrosive. It is also very dense and has a high boiling point. Sulphuric acid is produced by the reaction of sulphur dioxide and oxygen in the presence of a catalyst. It is a major industrial chemical and is used in a wide variety of applications, including the production of fertilizers, detergents, and plastics.
Sulphuric acid is a hazardous substance and can cause serious burns if it comes into contact with skin or eyes. It can also be harmful if inhaled or ingested. It is important to take precautions when handling sulphuric acid and to wear protective clothing and equipment.
