Sulphuric and ethanoic acid. Comparison of a strong and a weak acid. Sulphuric acid (H2SO4) is an important industrial chemical. It is used in petroleum refining and paint and fertiliser production. It is also a dehydrating and oxidising agent. Ethanoic acid (CH3COOH) is also known as acetic acid and is present in vinegar. It is a far weaker acid. It is used in the manufacture of dyes and plastics and as a food additive (E260).
