Which of the following acids is found in ant's sting ?

  • A.Ascorbic acid
  • B.Formic acid
  • C.Oxalic acid
  • D.Acetic acid

Answer: B

An ant's sting contains formic acid.

When an ant stings, it injects formic acid (methanoic acid), which causes pain and irritation. Its name comes from the Latin formica, ant. Rubbing a mild base such as baking soda on the sting neutralises the acid and gives relief.

Ascorbic acid is vitamin C, found in citrus fruits. Oxalic acid occurs in tomatoes and spinach. Acetic acid is the acid of vinegar.
