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 only a small amount is present. Tasting an unknown chemical can therefore cause burns, poisoning, or other injury, so it is never an acceptable identification method. Safe identification uses approved indicators, pH paper, or other supervised tests. The colour and taste of a substance are not reliable criteria. Thus option A is correct.
