What is precipitated after evaporating and concentrating a mixed solution of ammonium bisulfate and sulfuric acid?

Thread Content

After mixing a 22% by mass solution of (NH4)2SO4 with another solution (59.5% by mass of NH4HSO4 and 17.5% by mass of H2SO4) in a 1:1 ratio, and then evaporating the mixture to concentrate it and induce crystallization, what is formed – sulfuric acid or ammonium bisulfate? I think it should be ammonium bisulfate; I hope experts can give me some advice

Both sulfuric acid AN and ammonium bisulfate will precipitate, but a higher proportion of sulfuric acid AN precipitates, as its solubility in water is lower than that of ammonium bisulfate; an accurate determination requires consulting a phase diagram.

But this is in an acidic solution
