Pisikal iran Kablian: Say sodium dithionite et niklasipika bilang Grade 1 ya mainomay ya napoolan. Kabkabat met iya bilang Rongalite Diad komersyo, walad duaran klase: Na2S2O4·2H2O tan say anhydrous Na2S2O4. Say inmuna et pinon amputin kristal, bangta say komadua et amputin duyaw a pulbos. Say relatibon densidad to et 2.3-2.4. Nabubulok itan no ambetel, natunaw ed ambetel a danum balet nabubulok ed ambetel a danum. Ag-itan natunaw ed ethanol. Say aqueous solution to et agmalet tan walaan na mabiskeg a reducing properties, kanian ipapasen itan ya mabiskeg ya reducing agent.
No nipaarap ed dagem, mainomay ton nasepsep so oksihena tan man-oxidize. Mainomay met itan ya onsepsep na danum, ya mamapawala na petang tan onkakapuy. Sarag ton sepsepen so oxygen manlapud dagem, manporma na bukol, tan mangipaway na makapasinagem ya angob.
Na₂S₂O₄ + 2H₂O + O₂ → 2NaHSO₄ + 2[H]
Say pampetang odino pakapitongtong ed lukas ya ngalab et nayarin pansengegan na pakapoolan. Say temperatura na auto-ignition to et 250°C. Say pidedeneng ed danum et makapangipaway na baleg a petang tan napoolan ya hydrogen tan hydrogen sulfide gas, ya pansengegan na maksil a panagpoolan. Say pidedeneng ed saray oxidizer, daiset a danum, odino say pansepsep na danum ya mamapawala na petang et nayarin pansengegan na duyaw ya asewek, panagpoolan, odino anggan panagsabog.
Mangiiter kami na sarili min sodium dithionite raw materials pian naseguro so malet ya pangiter manlapud lapuan, ya ag kami mapaga ed oras na pangiter. Pindoten dia pian nawalaan na kompetisyon iran presyo.
