Explanation:
Sulfurous acid has the formula H2SO3 and the molecular weight of 82.075 g/mol. Its CAS number is 7782-99-2. There is no clear evidence that sulfurous acid exists in solution, but the molecule has been detected in the gas phase. The conjugate bases of this elusive acid are, however, common anions: bisulfite (or hydrogensulfite) = HSO3− and sulfite, SO3=. Bisulfite salts are typically prepared by treatment of alkaline solutions with excess sulfur dioxide:
SO2 + NaOH ⇒ NaHSO3
