Chemical Reactions of Sodium Bisulfate:
The hydrated sodium bisulfate first dehydrates and then separates from the water molecule which is attached to Sodium Bisulfate at 60°C temperature.
Sodium Bisulfate is allowed to cool.
Heating Sodium Bisulfate to 290 °C produces sodium pyrosulfate which is nothing but an absolute colourless salt:

Production of SODIUM BISULFATE:
Sodium bisulfate is produced as an intermediate in the Mannheim process, an industrial process involving the reaction of sodium chloride and sulfuric acid.
This step is highly exothermic.
The liquid sodium bisulfate is sprayed and cooled so that it forms a solid bead.
The hydrogen chloride gas is dissolved in water to produce hydrochloric acid as a useful coproduct of the reaction.
Although not of commercial interest, sodium bisulfate can be generated as a byproduct of the production of many other mineral acids via the reaction of their sodium salts with an excess of sulfuric acid.
The acids HX produced have a lower boiling point than the reactants and are separated from the reaction mixture by distillation.
