Sodium bisulfate : Preparation , Physical & Chemical Property , uses , storage condition , chemical incompatibility.

   Sodium bisulfate          [NaHSO₄]  Overview Sodium bisulfate is an acidic salt of sulfuric acid and is also known as sodium hydrogen sulfate. The chemical formula of sodium bisulfate is NaHSO 4  and its molar mass is 120.06 g/mol. It also exists as a monohydrate salt (with one molecule of water) with the molar mass of 138.07 g/mol. It is the monosodium salt of the diprotic sulfuric acid. It is composed of the sodium cation (Na + ) and bisulfate anion (HSO 4 - ), which has the sulfur atom bonded to three oxygen atoms and one hydroxyl group. It is a dry granular product that can be safely shipped and stored. The anhydrous form is hygroscopic. *Preparation* Sodium bisulphate is prepared by passing Sulphur Dioxide into a solution of sodium carbonate till the solution is saturated with Sulphur Dioxide first Sulphur Dioxide dissolved into water to form sulfuric acid. SO₂ + 2H₂O  →  H₂SO₄ + H₂↑ 2H₂SO₄ + Na₂CO₃  →  2NaHSO₄ + H...
