Sodium Sulfite yog yooj yim weathered thiab oxidized rau sodium sulfate nyob rau hauv huab cua.Posts ntawm crystalline dej ntawm 150 ℃.Tom qab tshav kub, nws melts mus rau hauv ib tug sib tov ntawm sodium sulfide thiab sodium sulfate.Qhov ceev ntawm anhydrous teeb meem yog 2.633.Nws oxidizes qeeb qeeb tshaj li hydrate thiab tsis muaj kev hloov nyob rau hauv qhuav cua. mus rau hauv cov ntsev sib tov thiab tso tawm sulfur dioxide.Sodium sulfite muaj zog reducibility, thiab tuaj yeem txo cov tooj liab ions mus rau cuprous ions (sulfite tuaj yeem tsim cov complexes nrog cuprous ions thiab stabilize), thiab tuaj yeem txo cov oxidants tsis muaj zog xws li phosphotungstic acid.Sodium sulfite thiab nws cov hydrogen ntsev tuaj yeem siv rau hauv cov dej me me kom tshem tawm cov dej peroxide, do cov tshuaj tiv thaiv nrog kub kub thiab faib cov kua, ether txheej yog qhuav nrog ceev cov txiv qaub, rau ib co tshuaj tiv thaiv uas tsis tshua muaj yuav tsum).Nws yuav tsum neutralized nrog hydrogen sulfide.
Ib feem ntawm cov kev sib npaug sib npaug:
1. tiam:
SO2+2NaOH===Na2SO3+H2O
H2SO3 + Na2CO3 = = = sau Na2SO3 + CO2 + H2O
2 nahso3 = = delta = = Na2SO3 + H2O + SO2 sau
2. Kev txo qis:
3 na2so3 hno3 + 2 + 2 = = = = 3 na2so4 no write + H2O
2Na2SO3+O2===2Na2SO4
3. Cua sov:
4 na2so3 = = delta = = Na2S + 3 na2so4
4. Oxidation:
Na2SO3 + 3 h2s = = = = 3 s left + Na2S + 3 h2o [1]
Kev npaj chav kuaj
Cov tshuaj sodium carbonate yog rhuab mus rau 40 ℃ thiab saturated nrog sulfur dioxide, ces tib tus nqi ntawm sodium carbonate tov yog ntxiv, thiab cov tshuaj yog crystallized nyob rau hauv lub mob ntawm tsis txhob sib cuag nrog huab cua.
