Question

A first-aid manual suggests that vinegar should be used to treat wasp stings and baking soda for bee stings. What does this information tell you about the chemical nature of:

1. wasp stings?
2. bee stings?

Answer 1

This information tells us that these insect venoms rely on opposite pH levels. Through the process of neutralisation, an acid balances a base to provide relief.

1. Wasp stings are alkaline (basic) in nature. They are treated with vinegar (acetic acid) to neutralise the venom and soothe the sting.
2. Bee stings are acidic in nature. They are treated with baking soda (sodium bicarbonate, a mild base) to neutralise the venom and relieve the pain.
