Question

Why does one feels pain and irritation when stung by honey-bee?
Rubbing of baking soda on the stung area gives relief. How?

Hint:

Honey-bee sting \(\Rightarrow\) acidic (formic acid). Baking soda \(\Rightarrow\) basic (NaHCO₃). Base neutralizes acid \(\Rightarrow\) relief. Remember: Bee sting = acid, Ant sting = acid, Wasp sting = alkaline (different treatment).

Why Does One Feel Pain and Irritation When Stung by a Honey Bee?

When a honey bee stings, it injects venom into the skin through its stinger. This venom contains certain chemicals such as formic acid and other irritating substances. These chemicals cause a local inflammatory reaction in the body.

The effects of the venom include:

– Stimulation of pain receptors in the skin.
– Redness and swelling due to increased blood flow.
– Irritation and burning sensation at the site of the sting.
– Sometimes itching or mild allergic reaction.

The acidic nature of the venom is mainly responsible for the sharp pain and irritation felt immediately after the sting.

How Does Rubbing Baking Soda Provide Relief?

Baking soda (sodium bicarbonate) is a mild base. Since the bee venom is acidic in nature, applying baking soda helps neutralize the acid.

The neutralization reaction between the acid in the venom and the base (baking soda):

– Reduces the acidic effect of the venom.
– Decreases irritation and burning sensation.
– Helps in reducing swelling and discomfort.

Thus, rubbing baking soda on the affected area provides relief by neutralizing the acidic venom.

Conclusion:
Pain and irritation from a honey bee sting occur because acidic venom is injected into the skin. Baking soda, being basic in nature, neutralizes the acid and reduces pain and irritation.
