Which of the following is a common example of a corrosive substance?

The choice of sulfuric acid as a common example of a corrosive substance is based on its chemical properties and behavior. Corrosive substances are characterized by their ability to damage or destroy living tissue and materials upon contact. Sulfuric acid, a strongly acidic compound, can cause severe burns and tissue damage when it comes into contact with skin or other organic materials. It reacts significantly with metals and other substances, leading to degradation or destruction.

In contrast, sodium chloride (common table salt) is generally not corrosive and is safe to handle. Hydrogen peroxide, while it can have corrosive effects at high concentrations, is primarily known for its oxidizing properties rather than being classified strictly as a corrosive agent. Oxygen, being a gas and an essential element for combustion and respiration, does not exhibit corrosive characteristics in itself.

Therefore, sulfuric acid stands out clearly as a well-known corrosive substance due to its highly reactive nature and the serious hazards it poses in various environments.
