  4. The last step is the condensation of the sulfuric acid to liquid 97–98% H 2 SO 4: H 2 SO 4 (g) → H 2 SO 4 (l) (−69 kJ/mol) Other methods. Another method is the less well-known metabisulfite method, in which metabisulfite is placed at the bottom of a beaker, and molar concentration hydrochloric acid .
