You may see this hazard pictogram on the side of a bottle of concentrated acid. What does it mean? (A) Burning, (B) corrosive, (C) irritant, (D) harmful, (E) toxic.

We encounter lots of acids in our everyday lives. Lemons, vinegar, yogurt, and batteries all contain acids. While some acids are harmless, other acids, particularly concentrated acids that we might use in the laboratory, must be handled with caution because they can cause damage to skin and other materials. These concentrated acids often have hazard pictograms written on their label, like the one shown. This pictogram shows that when the substance is poured on a material or human skin, it can cause damage. This pictogram indicates that the substance is corrosive.

A substance that is corrosive has high reactivity that causes damage upon contact with other materials. Some other hazard pictograms that we might encounter warn us if a chemical is an irritant, toxic, a health hazard, or flammable.

In conclusion, the hazard pictogram shown that often appears on the side of a bottle of concentrated acid means that the substance is corrosive, answer choice (B).
