Why should acids or bases not be identified by taste in a laboratory?
Answer and explanation
Correct answer: They can be harmful
Laboratory chemicals may be corrosive, poisonous, or otherwise harmful, even when only a small quantity is present. Tasting an unknown acid or base can cause burns, poisoning, or injury to the mouth and digestive system, so it is never an acceptable identification method. Safe testing uses suitable indicators, pH paper, or a teacher-approved procedure. The other options are false: acids and bases are not always sweet, may be colourless, and can have strong effects.
