Sodium nitrite is used as a medication together with sodium thiosulfate to treat cyanide poisoning. [26] It is recommended only in severe cases of cyanide poisoning and has largely been replaced by use of hydroxocobalamin , [ 27 ] a form of vitamin B12 , but given in much higher doses than needed nutritionally.

The sulfate nitrates are a family of double salts that contain both sulfate and nitrate ions (NO 3 −, SO 4 2−).They are in the class of mixed anion compounds.A few rare minerals are in this class.
Sodium nitrate – NaNO 3; Sodium nitrite – NaNO 2; Sodium nitroprusside – Na 2 [Fe(CN) 5 NO]·2H 2 O; ... Sodium sulfite – Na 2 SO 3; Sodium tartrate – C 4 H ...
The tables below provides information on the variation of solubility of different substances (mostly inorganic compounds) in water with temperature, at one atmosphere pressure.
It has a complex composition containing more than a dozen aromatic compounds, but the principal components are inorganic salts (sodium sulfate, sodium sulfite, sodium nitrite and sodium nitrate) and sulfonated nitroaromatics. [citation needed]
Sodium sulfite (sodium sulphite) is the inorganic compound with the chemical formula Na 2 SO 3. A white, water-soluble solid, it is used commercially as an antioxidant and preservative. It is also suitable for the softening of lignin in the pulping and refining processes of wood and lignocellulosic materials. [1]
Sulfites or sulphites are compounds that contain the sulfite ion (or the sulfate(IV) ion, from its correct systematic name), SO 2− 3. The sulfite ion is the conjugate base of bisulfite. Although its acid (sulfurous acid) is elusive, [1] its salts are widely used. Sulfites are substances that naturally occur in some foods and the human body.
Thus, solutions of sodium dithionite cannot be stored for a long period of time. [3] Anhydrous sodium dithionite decomposes to sodium sulfate and sulfur dioxide above 90 °C in the air. In absence of air, it decomposes quickly above 150 °C to sodium sulfite, sodium thiosulfate, sulfur dioxide and trace amount of sulfur.
