A substance that is able to destroy metal through chemical action is called what?

• A. Corrosive
• B. Corrosion
• C. Combustible
• D. Homogeneous

Answer: (A)

The main idea is about a substance that can chemically attack and wear away metal. A substance that can destroy metal through chemical action is described as corrosive. This term names the property of the substance—its ability to react with and break down metal surfaces, often by forming new compounds or releasing gases. The process of metal being worn away by chemical action is called corrosion, but that describes what happens, not the substance itself. The other terms don’t fit: combustible means something that can burn, and homogeneous refers to uniform composition, neither of which describe a substance that chemically destroys metal.
