Synthesis of sodium bisulfite (sodium hydrogen sulfite)

Preparation of sodium bisulfite

Sodium bisulfite is prepared by saturating sodium carbonate solution with sulfur dioxide.

Preparation of sodium bisulfite

Preparation of sodium bisulfite

50 g of copper tacks or clippings are heated with 200 g of concentrated sulfuric acid in a flask, with gas outlet tube. Obtained sulfur dioxide gas is first passed through a washing bottle containing water, then into a flask containing a solution of pure crystallized sodium carbonate. The saturation of sodium carbonate solution with sulfur dioxide is continued until the evolution of carbon dioxide ceases. When the reaction is complete, water is removed in vacuum by evaporation until the sodium bisulfite starts to crystallize. The solution is cooled, filtered and the crystals are washed with small amount of cold water, ethyl alcohol. Finnaly sodium bisulfite is dried in vacuum desiccator over anhydrous calcium chloride.
