Why should acids or bases not be identified by taste in a laboratory?
Answer and explanation
Correct answer: Many acids and bases can be harmful
The governing concept is laboratory safety and the controlled identification of chemicals. Acids and bases can be corrosive, poisonous or irritating even in small amounts, so tasting an unknown substance may cause burns or poisoning. Safe tests include suitable indicators, pH paper and teacher-approved procedures. Thus option A is correct. Taste is not always wrong, but it is unsafe; the other statements are scientifically overgeneralized or irrelevant.
