Model Answer

Vinegar contains ethanoic acid (acetic acid), which is a carboxylic acid. It is a weak acid.

Source: Properties of Ethanoic Acid, Chapter 4

Explanation

The examiner expects two pieces of information: the specific name (ethanoic/acetic acid) and its type (carboxylic acid). Mentioning it is a weak acid is a bonus but not strictly required for 1 mark. Avoid writing more than one line.
