Sodium metabisulfite waa budo cad ama jaalle ah oo crystalline ah ama kiristaalo yar oo leh ur xooggan oo SO2 ah. Xalkeeda biyaha ku jira waa aashito wuxuuna sii daayaa SO2 marka uu la kulmo aashito xooggan, taasoo soo saarta cusbo u dhiganta. Haddii hawada lagu daayo muddo dheer, waxay oksaydhaysaa Na2S2O6, sidaa darteed badeecadan lama kaydin karo muddo dheer.
Isticmaalka
Waxaa loo isticmaalaa sidii ilaaliyeyaal, wakiillo caday ah, iyo wakiillo dabacsan oo ku jira habaynta cuntada. Sodium metabisulfite waxaa loo isticmaalaa warshadaha sida daabacaadda iyo rinjiyeynta, isku-darka dabiiciga ah, daabacaadda, sameynta maqaarka, daawooyinka, iwm; Sodium metabisulfite waxaa loo isticmaalaa warshadaha kiimikada iyo daawooyinka si loo soo saaro budada caymiska, sulfamethoxazole metamaterial, caprolactam, iyo sidoo kale nadiifinta chloroform, phenylpropanoid sulfone, iyo benzaldehyde. Waxaa loo isticmaalaa sidii walax hagaajin ah warshadaha sawir qaadista. Warshadaha basbaaska waxaa loo isticmaalaa in lagu soo saaro vanillin. Waxaa loo isticmaalaa sidii ilaaliye warshadaha soo saarista, isku-darka caagga ah, iyo wakiilka dechlorination ee dharka cudbiga la caddeeyey. Dhexdhexaadiyeyaasha dabiiciga ah, midabaynta, maqaarka loo isticmaalo sidii wakiillo yareeya, oo loo isticmaalo warshadaha electroplating, daaweynta biyaha wasakhda ah ee beeraha saliidda, waxaana loo isticmaalaa sidii wakiillo macdan qodis ah oo ku jira macdanaha.
