H2SO3 is an unstable weak acid. It may be decomposed when the temperature is increased or the concentration is increased. When the concentration of sulfurous acid in the solution is high to a certain extent, it will be decomposed. Therefore, sulfurous acid can only exist in the dilute solution. Therefore, sulfurous acid produced by complete reaction is generally written as SO2 and H2O
