Izakhiwo Zomzimba: I-Sodium dithionite ihlukaniswa njengento evuthayo yeBanga 1. Yaziwa nangokuthi i-Rongalite Ngokwezentengiselwano, ikhona ngezindlela ezimbili: i-Na₂S₂O₄·2H₂O kanye ne-Na₂S₂O₄ engangenisi amanzi. Eyokuqala iyikristalu emhlophe ecolekile, kanti eyesibili iyimpuphu ephuzi ekhanyayo. Ubuningi bayo obuhlobene bungu-2.3-2.4. Iyabola uma ishisa kakhulu, incibilika emanzini abandayo kodwa ibola emanzini ashisayo. Ayincibiliki ku-ethanol. Isixazululo sayo samanzi asizinzile futhi sinezakhiwo zokunciphisa ezinamandla kakhulu, okusihlukanisa njenge-ejenti yokunciphisa enamandla.
Uma ibekwe emoyeni, imunca kalula umoya-mpilo futhi i-oxidize. Imunca kalula nomswakama, ikhiqize ukushisa futhi ibole. Ingamunca umoya-mpilo emoyeni, yakhe amaqhubu, futhi ikhiphe iphunga elimnandi elimuncu.
Na₂S₂O₄ + 2H₂O + O₂ → 2NaHSO₄ + 2[H]
Ukushisa noma ukuthinta ilangabi elivulekile kungabangela ukusha. Izinga lokushisa layo lokushisa ngokuzenzakalelayo lingu-250°C. Ukuthintana namanzi kungakhipha inani elikhulu lokushisa kanye negesi ye-hydrogen ne-hydrogen sulfide evuthayo, okuholela ekushiseni okunamandla. Ukuthintana nama-oxidizer, amanzi amancane, noma ukumuncwa komswakama okukhiqiza ukushisa kungabangela intuthu ephuzi, ukusha, noma ngisho nokuqhuma.
Sihlinzeka ngezinto zethu zokusetshenziswa ze-sodium dithionite ukuqinisekisa ukulethwa okuzinzile okuvela emthonjeni, ngaphandle kokukhathazeka ngesikhathi sokulethwa. Chofoza lapha ukuze uthole amanani ancintisanayo.
