What is Sodium Bisulfate?

Sodium bisulfate is an acidic salt of the sulfuric acid and the other name for this chemical compound is sodium hydrogen sulfate. The chemical formula for the compound is NaHSO4 and the molecular weight is 120.06 g/mol. If it exists in the monohydrate state then the molecular weight becomes 138.07 g/mol.

Sodium Bisulfate Chemical Structure

The chemical structure is given below where one sodium cation and bisulfate anion are connected together. The sulfur atom is placed in the center and bonded with three other oxygen atoms and one hydroxyl group too.

Sodium Bisulfate Formula

The product can be prepared for industry usage by partial neutralization of the sulfuric acid with an equimolar amount i.e. (1:1 ratio) of sodium hydroxide (NaOH) or sodium chloride (NaCl).

Sodium Bisulfate Formula NaHSO4

NaOH + H2SO4 → NaHSO4 + H2O

The product is available in the anhydrous form and monohydrate state too. Both have different densities and usage. Anhydrous Sodium bisulfate is white in color with a density of 2.74 g/mL and melting point of 315 °C. And the monohydrate Sodium bisulfate is a white granular solid with a density of 1.8 g/mL and a melting point of 59 °C. This is a dry acid so safe for shipping and the storage.

About Sodium Bisulfate

The chemical compound dissolves quickly in water and reacts quickly as the oxidizing agent.  Under stable temperature and pressure conditions, it will decompose when exposed to water. The major uses of the product include household cleaning, food disinfectant, household cleaning, pH control and more. Because of its strong acidic nature, it may cause irritation to eyes or skin etc. when swallowed in large quantity, it becomes toxic leads to diarrhea and vomiting.
