Why is it wrong to treat a wasp sting with baking soda solution?
Advertisements
उत्तर
When a wasp stings a person, it injects an alkaline solution into the skin, causing severe pain and irritation. The alkali has to be neutralised with an acid, not a base. If we apply a baking soda solution, which is a weak base, it worsens the pain. Hence, it is wrong to treat a wasp sting with a baking soda solution.
