Detailed Product Description:

Sodium bisulfate (aka, sodium hydrogen sulfate) is a hygroscopic

compound.  Its melting point is poorly defined because it begins to

decompose into sodium pyrosulfate and water before it reaches its

melting point.


Solutions of sodium bisulfate are acidic, with a 1M solution having

pH of 1.4.  In some applications, such solutions can be used instead

of sulfuric acid solution.  For example, from a solution of sodium

bisulfate and sodium acetate it is possible to distill acetic acid.  Sodium

bisulfate solutions will also liberate CO2 from most carbonates.


Sodium bisulfate behaves, to some degree, as if it were a complex of

sodium sulfate with sulfuric acid.  This is evident if either the anhydrous

form or the monohydrate come in contact with ethanol, which causes

them to separate into those two components.



Often used as an ingredient in foods such as dressings or sauces.  Also

Used in fruit and vegetable processing and as a preservative for soil

and water samples in analytical laboratory analysis.

Commonly used in swimming pools for lowering the pH (reducing
