Which type of substance is useful to reduce the acidic effect of a nettle sting?
Answer and explanation
Correct answer: Mild base
Nettle stings may introduce acidic substances that cause irritation. The governing concept is neutralisation: an acid is reduced by reacting with a suitable base. Therefore, a mild base is the most appropriate choice because it can counteract the acidic effect without adding more acid. A strong acid or acidic juice would worsen the condition, while neutral oil does not neutralise the acid.
