Which taste in curd and sour foods indicates the presence of an acid?
Answer and explanation
Correct answer: Sour taste
Many acids found in foods have a sour taste, which is a common preliminary property used to identify acidic substances. Curd contains lactic acid, and this contributes to its sour taste; hence option B is correct. Sweetness, bitterness, and saltiness are not the characteristic taste indicated here. Substances must never be tasted in a laboratory merely for identification.
