An acidic substance in an ant sting causes irritation. Which substance is most suitable?
Answer and explanation
Correct answer: Mild solution of baking soda
When the irritating substance from an ant sting is treated as acidic, a mild base is the appropriate chemical counteragent. Baking soda, sodium hydrogen carbonate (NaHCO₃), provides mild alkalinity and can neutralise part of the acid, reducing its irritating effect. Lemon juice and vinegar are acidic, so they would not neutralise the acid, and adding a stronger acid would worsen irritation. Therefore option A is the best answer.
