Hauj lwm
Sodium sulfite yog ib qho inorganic compound nrog cov tshuaj formula Na₂SO₃. Nws zoo nkaus li dawb, dej-soluble khoom thiab feem ntau yog siv los ua antioxidant thiab preservative. Qhov kev sib xyaw no kuj tseem siv rau hauv ntau cov txheej txheem kev lag luam, suav nrog cov softening ntawm lignin hauv pulping thiab refining txheej txheem ntawm ntoo thiab lignocellulosic cov ntaub ntawv.
