Why does applying a mild basic substance give relief when an ant sting contains an acidic substance?
Answer and explanation
Correct answer: The acid is neutralised
The governing concept is neutralisation: an acid reacts with a base to reduce its acidic properties, usually forming salt and water. If the irritating material from an ant sting is acidic, a suitable mild base can react with some of it and reduce the acidity at the skin surface, giving relief. Therefore option A is correct. Options B and D contradict the acid–base reaction, while C is scientifically impossible. Only a safe, mild substance should be used, not a concentrated chemical.
