Question

Vinegar is ______.

Options

• 10% Acetic acid

• 80% Acetic acid

• Pure acetic acid

• 4-6% acetic acid

Answer 1

Vinegar is 4-6% acetic acid.

Explanation:

Vinegar is a dilute aqueous solution consisting primarily of 4% to 6% acetic acid (ethanoic acid) by volume, with the remaining portion being water and trace flavour compounds. Industrially, acetic acid bacteria produce it by fermenting ethanol. This specific low concentration provides the characteristic mild, sour taste and acidic pH necessary for its widespread use as a food preservative and cooking ingredient.
