Why is baking soda useful for reducing irritation from an ant sting?
Answer and explanation
Correct answer: It neutralises formic acid
The governing concept is neutralisation of an acid by a mild base. Ant venom commonly contains formic acid, which contributes to the burning sensation at the sting site. Baking soda, sodium hydrogen carbonate, is mildly basic and can react with or neutralise part of the acid, reducing irritation. Therefore option A is correct. The remaining choices either reverse the chemistry or describe impossible transformations.
