प्रश्न
Name the acid present in ant sting and give its chemical formula. Also give the common method to get relief from the discomfort caused by the ant sting.
उत्तर
The acid present in ant sting is methanoic acid or formic acid. Its chemical formula is HCOOH. Being poisonous in nature, it causes pain and irritation. Even blisters may appear on the stung area. One should immediately rub the stung area with a mild base like baking soda (NaHCO3). It will react with formic acid to form salt and water. Its poisonous effect will be completely neutralised.
`underset("Methanoic acid")("HCOOH") + "NaHCO"_3 -> underset("Sod. methanoate")("HCOONa") + "CO"_2 + "H"_2"O"`
Remember : We should never apply sodium hydroxide pellets or solution directly or the affected portion. Being strongly corrosive in nature, it will aggrievate pain by forming more blisters. However, sodium hydrogen carbonate can be applied.
