|---|---|---|---|
| Natural Sources | Acids | ||
| (A) | Tamarind | (I) | Oxalic acid |
| (B) | Tomato | (II) | Methanoic acid |
| (C) | Ant sting | (III) | Citric acid |
| (D) | Lemon | (IV) | Tartaric acid |
Choose the correct answer from the options given below:
Answer & explanation
Correct answer: option 3
The correct answer is Option (3) → (A)-(IV), (B)-(I), (C)-(II), (D)-(III)
Many sour foods and some stings owe their effect to a naturally occurring acid. Each source in List-I is matched with the acid it contains.
(A) Tamarind — this matches (IV) Tartaric acid. The sour taste of tamarind comes mainly from tartaric acid.
(B) Tomato — this matches (I) Oxalic acid. Tomatoes contain oxalic acid (with some citric acid).
(C) Ant sting — this matches (II) Methanoic acid. An ant injects methanoic acid (formic acid), which causes the pain; rubbing a mild base such as baking soda eases it.
(D) Lemon — this matches (III) Citric acid. Lemons and other citrus fruits get their sourness from citric acid.
