Why is identifying an acid by taste unacceptable in the laboratory?
Answer and explanation
Correct answer: Many acids are harmful and indicators are safe
The governing concept is laboratory safety and the use of chemical indicators. Many acids are corrosive or toxic, so tasting even a small amount may burn tissues or cause poisoning. Litmus paper, universal indicator, or a pH strip can test acidic character without direct contact. Therefore option A is correct; B is false because acids may have tastes, while C and D incorrectly treat taste or indicators as unsuitable tests.
