Help: What is the state of sodium sulfate in concentrated sulfuric acid?

Thread Content

When a strong acid is used to produce a weak acid, and after the weak acid is distilled off, what is the state of the excess concentrated sulfuric acid and the sodium sulfate formed in the reaction vessel? No water is involved in the process. Does anyone know? How should these residues from the kettles be disposed of?

H2SO4+Na2SO3=Na2SO4+H2O+SO2

It is generally a solid crystal that, when exposed to air, absorbs the moisture from the air and partially deliquesces, forming a pale green liquid. Treatment method: Rinse with plenty of clean water
