(b) What happens during a wasp sting? What is its remedy?

a) When a bee stings a person, it injects an acidic solution into the person’s skin. This causes severe pain and irritation. The remedy is to apply a baking soda solution (sodium hydrogen carbonate solution, which is a base). The solution soothes the pain by neutralising the acid.

(b) When a wasp stings a person, it inserts an alkaline solution into the person's skin. This causes severe pain and irritation. The remedy is to apply a weak acid, such as vinegar, to the wound. The acid neutralises the alkaline solution and soothes the pain.
