Why is it wrong to identify acidic and basic substances by directly tasting them?
Answer and explanation
Correct answer: Because they may be harmful or corrosive
The governing concept is laboratory safety. Acids and bases can irritate or damage body tissues, and concentrated substances may be corrosive or poisonous. Therefore directly tasting them is unsafe, making option A correct. The other choices are scientifically wrong: substances can have tastes, acids are not all sweet, and bases are not all sour. Indicators should be used instead.
