Discription:
Molecular Formula :Na2S2O5
Molecule Weight :190.12
CAS NO .:7681-57-4
Appearance :White Free white crystalline powder
Property: Dechlorination Sodium Metabisulfite is:
white or light yellow crystal powder, a strong smell of sulfur dioxide,relative density is 1.4, easy to dissolve in water
and glycerin, water solution.
It has acidity,and its solubility will become large while raising the temperature and is less to dissolve in ethanol.
Appearance: Pure White Crystalline Powder .
Sodium metabisulfite is a white or yellow crystalline powder or a small crystal with a strong SO2 odor. The specific gravity is 1.4. It dissolves in water and the aqueous solution is acidic. When it comes into contact with strong acid, SO2 is released and the corresponding salt is generated. If it is left in the air for a long time, it is oxidized. As Na2S2O6, so the product can not exist for a long time. Above 150 degrees Celsius, SO2 is decomposed.
Synonyms: disodiummetabisulfite; disodiumpyrosulphite; fertisilo; metabisulfitedesodium; Sodiummetabisufite; sodiummetabisulfite(na2-s2o5); sodiumpyrosulfite(na2s2o5); Sodium dissulfite; Sodium disulphite; Sodium pyrosulphite
Application:
(1) Food Grade: Bleach agent (e.g. candies, cake, bamboo shoots, etc); Loose agent (e.g. bread, cracker etc);
Antiseptic and germicide (e.g. fruit juice, tinned food, brews, the cereals food is defended storage etc);
Inhibitor and freshen agent (e.g. day lily, seafood, fruit and vegetable etc).
