Which substance can be applied to reduce irritation from an ant sting?
Answer and explanation
Correct answer: Baking soda
The governing concept is acid-base neutralisation. An ant sting contains an acidic secretion, commonly associated with methanoic acid. Baking soda, or sodium hydrogen carbonate, is mildly basic; when applied appropriately, it can partially neutralise the acid and reduce irritation. Therefore option A is correct. Lemon juice, vinegar, and tamarind juice are acidic, so they would not provide the required neutralising effect. Any severe reaction requires medical attention rather than home treatment.
