Why is it wrong to identify an acid by taste in the laboratory?
Answer and explanation
Correct answer: Many acids are harmful and indicators are safer
The governing concept is laboratory safety: an unknown acid must never be tasted because even a small amount may burn tissues, poison the body, or cause other harm. Taste also cannot reliably identify an acid or measure its pH. Instead, a teacher-approved indicator such as litmus, universal indicator, or pH paper should be used. Therefore option A is correct; B, C, and D make scientifically unsafe or false claims.
