Lokha nayivezwa emoyeni, i-sodium hydrosulfite idonsa lula i-oksijini bese iyakhiqiza i-oksijini. Godu imunya umswakama, yenza ukutjhisa begodu irholele ekuwohlokeni. Ingahlangana ndawonye ngesikhathi idonsa i-oksijini yommoya bese ikhipha iphunga elinamandla le-esidi.
Na₂S₂O₄ + 2H₂O + O₂ → 2NaHSO₄ + 2[H]
Ukutjhisa nofana ukuvezwa elangabini elivulekileko kungabangela ukutjhisa, ngezinga lokutjhisa lokuvutha okuzenzakalelayo okungu-250°C. Ukuthintana namanzi kukhupha umtjhiso omnengi kanye namagesi avuthako afana ne-hydrogen ne-hydrogen sulfide, okurholela ekutjhiseni okukhulu. Lokha nayihlanganiswa nama-ejenti we-oksijini, amanzi amancani, nofana umoya omanzi, i-sodium hydrosulfite ingakhiqiza umtjhiso, ikhuphe intuthu ephuzi, itjhise, nofana iqhume.
Ngokusetjenziswa okuhlukahlukeneko, i-sodium hydrosulfite iqakathekile ekuhlanzeni iindwangu namaphepha, begodu isetjenziselwa nokubulunga ukudla. Iphinde inikeze ukusebenza okuhle khulu ekuhlanganisweni kwemithi, ukuhlanza i-elekthronikhi, ukususa umbala wamanzi angcolileko, nokunye. Tlika lapha ukuthola isevisi esezingeni eliphezulu nekhowuthi.
