Sodium bisulfite (sodium hydrogen sulfite) is a chemical compound with the chemical formula NaHSO 3. Sodium bisulfite is a food additive with E number E222. This salt of bisulfite can be prepared by bubbling sulfur dioxide in a solution of sodium carbonate in water.odium bisulfite is a food additive with E number E222. This salt of bisulfite can be prepared by bubbling sulfur dioxide in a solution of sodium carbonate in water.
Sodium phosphide, Na 3 P, is a black, ionic salt containing the alkali metal sodium and the phosphide anion. Na 3 P is a source of the highly reactive phosphide anion.It should not be confused with sodium phosphate, Na 3 PO 4.In addition to Na 3 P, five other binary compositions of sodium and phosphorus are known: NaP, Na 3 P 7, Na 3 P 11, NaP 7, and NaP 15.odium phosphide is highly dangerous releasing toxic phosphine upon hydrolysis, a process that is so exothermic that fires result. The USDOT has forbidden the transportation of Na 3 P on passenger aircraft, cargo only aircraft, and trains due to the potential fire and toxic hazards.
