It can substitute for baking soda (sodium bicarbonate) for those with a low-sodium diet, [4] and it is an ingredient in low-sodium baking powders. [5] [6] As an inexpensive, nontoxic base, it is widely used in diverse application to regulate pH or as a reagent. Examples include as buffering agent in medications, an additive in winemaking.
Sodium chloride is extensively used for anti-icing and de-icing and as a preservative; examples of the uses of sodium bicarbonate include baking, as a raising agent, and sodablasting. Along with potassium, many important medicines have sodium added to improve their bioavailability ; though potassium is the better ion in most cases, sodium is ...
Sodium bisulfite solutions can be prepared by treating a solution of suitable base, such as sodium hydroxide or sodium bicarbonate with sulfur dioxide. SO 2 + NaOH → NaHSO 3 SO 2 + NaHCO 3 → NaHSO 3 + CO 2. Attempts to crystallize the product yield sodium metabisulfite (also called sodium disulfite), Na 2 S 2 O 5. [6]
