Why should acids or bases not be identified by taste in a laboratory?
Answer and explanation
Correct answer: They can be harmful
Tasting a laboratory chemical is unsafe because acids and bases may be corrosive, poisonous, or irritating even in small quantities. Their taste is therefore not an acceptable identification method. A suitable indicator, pH paper, or another supervised laboratory test should be used instead. Option B is false because acids and bases are not always sweet; options C and D are also scientifically incorrect.
