Ikalowa mumlengalenga, sodium hydrosulfite imayamwa mpweya mosavuta ndikusungunuka. Imayamwanso chinyezi, ndikupanga kutentha ndikupangitsa kuti iwonongeke. Imatha kusonkhana pamodzi pamene ikuyamwa mpweya wa mlengalenga ndikutulutsa fungo la asidi lopweteka.
Na₂S₂O₄ + 2H₂O + O₂ → 2NaHSO₄ + 2[H]
Kutentha kapena kukhudzana ndi moto wotseguka kungayambitse kuyaka, ndi kutentha kodzidzimutsa kwa 250°C. Kukhudzana ndi madzi kumatulutsa kutentha kwakukulu ndi mpweya woyaka monga hydrogen ndi hydrogen sulfide, zomwe zimapangitsa kuyaka kwambiri. Mukaphatikiza ndi zinthu zosungunuka, madzi ochepa, kapena mpweya wonyowa, sodium hydrosulfite imatha kutulutsa kutentha, kutulutsa utsi wachikasu, kuyaka, kapena kuphulika.
Ndi ntchito zosiyanasiyana zodabwitsa, sodium hydrosulfite ndi yofunika kwambiri poyeretsa nsalu ndi mapepala, komanso imagwiritsidwa ntchito posunga chakudya. Imaperekanso ntchito yabwino kwambiri popanga mankhwala, kuyeretsa zamagetsi, kuchotsa utoto m'madzi otayira, ndi zina zambiri. Dinani apa kuti mupeze ntchito yabwino kwambiri komanso mtengo wake.
