Iipropati Zomzimba: I-Sodium dithionite ihlelwa njengesixhobo esivuthayo seBanga loku-1. Ikwaziwa njengeRongalite Ngokwezorhwebo, ikhona ngeendlela ezimbini: i-Na₂S₂O₄·2H₂O kunye ne-Na₂S₂O₄ engangenisi manzi. Eyokuqala yikristale emhlophe entle, ngelixa eyesibini ingumgubo otyheli okhanyayo. Ubuninzi bayo buyi-2.3-2.4. Iyabola xa ishushu ngobomvu, inyibilika emanzini abandayo kodwa ibola emanzini ashushu. Ayinyibiliki kwi-ethanol. Isisombululo sayo samanzi asizinzanga kwaye sineempawu zokunciphisa ezinamandla kakhulu, nto leyo eyenza ukuba ibe yiarhente yokunciphisa enamandla.
Xa ibekwe emoyeni, ifunxa ioksijini lula kwaye inyibilikise. Ikwafunxa umswakama lula, ivelise ubushushu kwaye yonakale. Ingafunxa ioksijini emoyeni, yenze amaqhuma, kwaye ikhuphe ivumba elimnandi elimuncu.
Na₂S₂O₄ + 2H₂O + O₂ → 2NaHSO₄ + 2[H]
Ukufudumeza okanye ukudibana nelangatye elivulekileyo kunokubangela ukutsha. Ubushushu bayo bokutsha buyi-250°C. Ukudibana namanzi kunokukhupha ubushushu obuninzi kunye negesi ye-hydrogen kunye ne-hydrogen sulfide evuthayo, nto leyo ekhokelela ekutsha okunamandla. Ukudibana ne-oxidizers, amanzi amancinci, okanye ukufunxwa kobushushu obuvelisa umswakama kunokubangela umsi otyheli, ukutsha, okanye nokuqhuma.
Sinikezela ngezinto zethu ze-sodium dithionite ukuze siqinisekise ukuba ukuhanjiswa okuzinzileyo kuvela kumthombo, ngaphandle kokukhathazeka ngexesha lokuhanjiswa. Cofa apha ukuze ufumane amaxabiso akhuphisanayo.
