Uma ibekwe emoyeni, i-sodium hydrosulfite imunca kalula umoya-mpilo futhi i-oxidize. Iphinde imunce umswakama, ikhiqize ukushisa futhi iholele ekuwohlokeni. Ingahlangana ndawonye ngenkathi imunca umoya-mpilo womoya-mpilo futhi ikhiphe iphunga elimnandi le-asidi.
Na₂S₂O₄ + 2H₂O + O₂ → 2NaHSO₄ + 2[H]
Ukushisa noma ukuchayeka elangeni elivulekile kungabangela ukusha, ngokushisa okuzenzakalelayo kokushisa okungu-250°C. Ukuthintana namanzi kukhipha inani elikhulu lokushisa kanye namagesi avuthayo njenge-hydrogen ne-hydrogen sulfide, okuholela ekushiseni okukhulu. Uma kuhlanganiswa nama-oxidizing agents, amanzi amancane, noma umoya omanzi, i-sodium hydrosulfite ingakhiqiza ukushisa, ikhiphe intuthu ephuzi, ishise, noma iqhume.
Njengoba inezinhlobo eziningi zezicelo, i-sodium hydrosulfite ibalulekile ekukhanyeni izindwangu nephepha, futhi isetshenziswa nasekulondolozweni kokudla. Iphinde inikeze ukusebenza okuhle kakhulu ekuhlanganiseni imithi, ekuhlanzeni izinto zikagesi, ekususeni umbala emanzini amdaka, nokuningi. Chofoza lapha ukuze uthole isevisi esezingeni eliphezulu kanye nesilinganiso.
