Xa ibekwe emoyeni, i-sodium hydrosulfite ifunxa ioksijini ngokulula kwaye inyibilikise. Ikwafunxa umswakama, ivelise ubushushu kwaye ikhokelele ekuwohlokeni. Ingahlangana kunye ngelixa ifunxa ioksijini esemoyeni kwaye ikhuphe ivumba elimnandi le-asidi.
Na₂S₂O₄ + 2H₂O + O₂ → 2NaHSO₄ + 2[H]
Ukufudumeza okanye ukuvezwa kwilangatye elivulekileyo kunokubangela ukutsha, kunye nobushushu bokutsha obuvela ngokungaziyo obuyi-250°C. Ukudibana namanzi kukhupha ubushushu obuninzi kunye neegesi ezinokutsha ezifana ne-hydrogen kunye ne-hydrogen sulfide, nto leyo ekhokelela ekutshiseni okukhulu. Xa zidityaniswe nee-oxidizing agents, amanzi amancinci, okanye umoya omanzi, i-sodium hydrosulfite inokuvelisa ubushushu, ikhuphe umsi otyheli, itshise, okanye ide iqhume.
Ngoluhlu olubanzi kakhulu lwezicelo, i-sodium hydrosulfite ibalulekile ekucoceni amalaphu nephepha, kwaye ikwasetyenziswa ekugcinweni kokutya. Ikwabonelela ngokusebenza okugqwesileyo ekuhlanganiseni amayeza, ukucoca nge-elektroniki, ukususa umbala emanzini amdaka, nokunye. Cofa apha ukuze ufumane inkonzo esemgangathweni ophezulu kunye nexabiso.
