Sulfurous Acid and Sodium Hydroxide
H2SO3 + 2NaOH → Na2SO3 + 2H2O
Ikhtisar
Sulfurous acid reacts with two equivalents of sodium hydroxide to form sodium sulfite and water. Sulfurous acid is formed when sulfur dioxide dissolves in water and is a diprotic acid. It is unstable and cannot be isolated as a pure substance.
