How can presence of NaHSO4 be confirmed? How it can different
from Na2SO4?

Well, Sodium bisulfate is an acid salt usually obtained as a
second product when we preparing hydrochloric acid whereas
Sodium sulfate is obtained by exact neutralization of Sodium
hydroxide and sulfuric acid. However, the two can be
differentiated easily. Since Sodium bisulfate is an acid salt,
it turns blue litmus red whereas Sodium sulfate is neutral
towards litmus. Actually, Sodium bisulfate (NaHSO4) acts as an
acid and even be used in the place of sulfuric acid sometimes or
where sulfuric acid cannot be used. For instance, sulfuric acid
does not attack aluminium oxide whereas when fusing with Sodium
bisulfate, it produces, sodium sulfate & aluminium sulfate. Hope
this is clear. Please let me know if you have any questions.

oh yes, even if it is at moderate concentration. Commercially,
they produce Aluminium sulfate by dissolving roasted aluminium
oxide in boiling sulfuric acid. This reaction only happen at
elevated temperature.
