Which of the following natural sources contains methanoic acid?
Answer & explanation
Correct answer: option 2
The correct answer is Option (2) → Nettle sting
Methanoic acid, better known as formic acid, is the substance in the sting of the nettle plant, and it is also what makes an ant’s bite smart — the name comes from formica, the Latin for ant.
The traditional remedy of rubbing a dock leaf on a nettle sting works because the leaf is mildly basic and neutralises the acid.
