Ko te konutai Sulfite he ngawari te rangi me te oxidized ki te konutai pūkawa ngāwha i roto i te rangi.Ko te ngaro o te wai tioata i te 150 ℃.I muri i te wera, ka rewa ki te ranunga o te konutai sulfide me te konutai pūkawa ngāwha.Ko te kiato o te mea anhydrous ko 2.633.It oxidizes nui atu āta atu i te hydrate me kahore he huringa i roto i te maroke rangi.Heat whakangao ngongo o te konutai pūkawa ngāwha, me te konutai whakangao ngongo whakangao. pirau ki nga tote e rite ana, ka tuku i te whanariki hauhā. Ko te konutai sulfite he kaha te whakaheke, a ka taea te whakaiti i nga katote parahi ki nga katote kapu (ka taea e te sulfite te hanga matatini me nga katote kapu me te whakapumau), ka taea hoki te whakaiti i nga waikura ngoikore penei i te waikawa phosphotungstic. Ko te konutai sulfite me tona tote hauwai ka taea te whakamahi ki te tango i nga peroxides o te taiwhanga wai me te taiwhanga o te taiwhanga wai iti. wera me te wehewehe i te wai, ka maroke te paparanga ether ki te kotakota tere, mo etahi tauhohenga me nga whakaritenga iti).Ka taea te whakakore ki te hauwai sulfide.
Wāhanga o te whārite tauhohenga:
1. Te whakatipuranga:
SO2+2NaOH===Na2SO3+H2O
H2SO3 + Na2CO3 = = = tuhia Na2SO3 + CO2 + H2O
2 nahso3 = = delta = = Na2SO3 + H2O + SO2 tuhia
2. Whakaiti:
3 na2so3 hno3 + 2 + 2 = = = = 3 na2so4 kore tuhi + H2O
2Na2SO3+O2====2Na2SO4
3. Te whakawera:
4 na2so3 = = delta = = Na2S + 3 na2so4
4. Hāoratanga:
Na2SO3 + 3 h2s = = = = 3 s i mahue + Na2S + 3 h2o [1]
Te whakarite taiwhanga
Ka whakamahanahia te wairewa konutai warowaiha ki te 40 ℃ ka kukū ki te whanariki hauhā, katahi ka taapirihia te nui o te wairewa konutai warowaiha, ka whakamaaramatia te otinga i raro i te ahua o te karo i te pa ki te hau.
