Why does applying baking soda on an ant sting give relief?
Answer and explanation
Correct answer: It neutralises the acid
An ant sting commonly contains methanoic acid, which causes local irritation. Baking soda, or sodium hydrogen carbonate, is mildly basic and can neutralise part of this acid when applied appropriately as a dilute paste. The reduced acidity helps lessen the burning sensation, so option A is correct. Increasing acid, causing rusting, or stopping gas is not the relevant chemical action.
