Sodium bisulfite (or sodium bisulphite, sodium hydrogen sulfite) is a chemical mixture with the approximate chemical formula NaHSO 3. Sodium bisulfite is not a real compound, [ 2 ] but a mixture of salts that dissolve in water to give solutions composed of sodium and bisulfite ions.
This lengthens the shelf life of the formulation, [6] although the sodium metabisulfite reacts with adrenaline, causing it to degrade and form epinephrine sulfonate. [8] In combination with sodium hydrosulfite it is used as a rust-stain remover [9] It is used in photography. [10] Concentrated sodium metabisulfite can be used to remove tree stumps.
The shelf lives when stored at ambient temperature have been reported as good. [7] ... Sodium bisulfite 85 °C [13] Diethyl malonate = 110 °C [14]
The bisulfite ion (IUPAC-recommended nomenclature: hydrogensulfite) is the ion HSO − 3. Salts containing the HSO − 3 ion are also known as "sulfite lyes". [1] Sodium bisulfite is used interchangeably with sodium metabisulfite (Na 2 S 2 O 5). Sodium metabisulfite dissolves in water to give a solution of Na + HSO − 3. Na 2 S 2 O 5 + H 2 O ...
The sodium and potassium salts of bisulfite are not available, but solid and solutions of the approximate formula NaHSO 3 and KHSO 3 are widely marketed as sodium bisulfite and potassium bisulfite. Closely related are the metabisulfite salts with formula Na 2 S 2 O 5 and K 2 S 2 O 5 , respectively sodium metabisulfite and potassium metabisulfite .
Sulfites that are allowed to be added in food in the US are sulfur dioxide, sodium sulfite, sodium bisulfite, potassium bisulfite, sodium metabisulfite, and potassium metabisulfite. [32] Products likely to contain sulfites at less than 10 ppm (fruits and alcoholic beverages) do not require ingredients labels, and the presence of sulfites ...
The best way to store vitamins for optimal shelf-life. Elements like heat, humidity, light, and air are the “main enemies of vitamin freshness,” says Blatner. “Keep them cool, dry, and out ...
