Why should acids and bases not be identified by taste in a laboratory?
Answer and explanation
Correct answer: They can be harmful
The governing concept is laboratory chemical safety. Acids and bases used in experiments may be corrosive, poisonous, or harmful even in small amounts, and their appearance cannot reliably reveal their danger. Tasting an unknown substance can injure the mouth, throat, or internal organs. Thus option A is correct. Safe identification should use an indicator such as litmus or pH paper under supervision; B, C, and D are scientifically false.
