Sodium Bisulfate Formula – Molecular, Structural and Chemical Formula

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.

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.
