Taw qhia
Lub npe: Sodium metabisulfite
CAS Nr: 7681-57-4
Cov mis mos molecular: Na2S2O5
Sodium metabisulfite tso tawm sulfur dioxide thiab tsim cov ntsev sib xws, thaum nws tiv nrog cov kua qaub. Yog tias nws muab tso rau hauv huab cua ntev, nws yuav raug oxidized rau hauv sodium sulfate, yog li sodium metabisulfite tsis tuaj yeem khaws cia rau lub sijhawm ntev.
