Why should acids or bases not be identified by taste in a laboratory?
Answer and explanation
Correct answer: They can be harmful
Laboratory acids and bases may be corrosive, poisonous, or irritating even when they are dilute or appear harmless. Tasting an unknown chemical can injure the mouth and digestive system and is therefore prohibited by laboratory safety rules. Option A is correct. Colour or sweetness cannot reliably identify a substance, and the claim that acids and bases have no effect is false. Indicators, pH paper, or approved testing methods should be used instead.
