Practice questions
Q1Which acid is present in a nettle sting?
Explanation
Methanoic acid, also called formic acid, is the acid commonly associated with the painful irritation caused by a nettle sting in school-level chemistry. Tartaric acid is associated with substances such as tamarind and grapes, not nettle stings. Oxalic acid is found in plants such as spinach and is not the standard answer here. Lactic acid is formed in muscles during anaerobic activity and is also linked with sour milk products, so it does not explain the sting of nettle.
