Sodium sulfite na-adị mfe ihu igwe na oxidized na sodium sulfate na air.Loss nke crystalline mmiri na 150 ℃. Mgbe okpomọkụ, ọ gbazee n'ime ngwakọta nke sodium sulfide na sodium sulfate.The njupụta nke anhydrous ihe bụ 2.633.It oxidizes ukwuu nwayọọ nwayọọ karịa hydrate na ọ dịghị mgbanwe na akọrọ sulf na sodium acid deposition. kọntaktị decomposition n'ime kwekọrọ ekwekọ salts na hapụ sọlfọ dioxide.Sodium sulfite nwere ike reducibility, na nwere ike ibelata ọla kọpa ions ka cuprous ion (sulfite nwere ike na-etolite ogige na cuprous ion na stabilize), na nwekwara ike belata adịghị ike oxidants dị ka phosphotungstic acid.Sodium sulfite na ya hydrogen nnu nwere ike iji wepụ peroxides nke ego nke ether mmiri na-akpali akpali (ad okpomọkụ ether bekee). kewaa mmiri mmiri, ether oyi akwa akpọnwụwo na ngwa ngwa wayo, maka ụfọdụ mmeghachi omume na ala chọrọ) .Ọ nwere ike neutralized na hydrogen sulfide.
Akụkụ nke nhazi mmeghachi omume:
1. Ọgbọ:
SO2+2NaOH===Na2SO3+H2O
H2SO3 + Na2CO3 = = dee Na2SO3 + CO2 + H2O
2 nahso3 = = delta = = Na2SO3 + H2O + SO2 dee
2. Mbelata:
3 na2so3 hno3 + 2 + 2 = = = 3 na2so4 enweghị dee + H2O
2Na2SO3+O2====2Na2SO4
3. The kpo oku:
4 na2so3 = = delta = = Na2S + 3 na2so4
4. Oxidation:
Na2SO3 + 3 h2s = = 3 s ekpe + Na2S + 3 h2o [1]
