Why should acids or bases not be identified by tasting them in a laboratory?
Answer and explanation
Correct answer: They can be harmful
Laboratory chemicals may be corrosive, poisonous, or irritating even when only a small quantity is present. Therefore tasting an unknown acid or base can injure the mouth, throat, or digestive system and is never an acceptable identification method. Indicators, universal indicator, or pH paper provide safer evidence of acidic or basic character. Since acids and bases can be harmful, option A is correct.
