Sodium Sulfite inogadziriswa nyore nyore uye yakasvibiswa kune sodium sulfate mumhepo.Kurasikirwa kwecrystalline mvura pa 150 ℃.Mushure mekupisa, inonyunguduka musanganiswa we sodium sulfide uye sodium sulfate.Kuwanda kweanhydrous nyaya ndeye 2.633.Iyo oxidizes zvakanyanya zvishoma nezvishoma mumhepo yakaoma uye haina kuchinja kwesodium sulfide uye haina shanduko ye commude airfide. sodium sulfate, uye yakasimba asidhi kuonana kuora muunoenderana munyu uye kusunungurwa sarufa dioxide.Sodium sulfite ane simba reducibility, uye anogona kuderedza mhangura ions kuti cuprous ions (sulfite anogona kuumba complexes pamwe cuprous ions uye kudzikamisa), uye anogonawo kuderedza utera oxidants akadai phosphotungstic acid.Sodium sulfite uye kushandiswa kwayo diki hydrogens munyu anogona kubudisa hydrogens peroksidi munyu anogona hydrogens hydrogen labobhoroksi inoshandiswa mu labotory hydrogen labobhori inogona kuumba ma complexes ane cuprous ions uye kugadzikana. huwandu hwemvura, kurunga mhinduro nekupisa nyoro uye kupatsanura mvura, iyo eteri layer yakaomeswa neraimu nekukurumidza, kune mamwe maitiro ane yakaderera zvinodiwa) .
Chikamu che reaction equation:
1. Chizvarwa:
SO2+2NaOH===Na2SO3+H2O
H2SO3 + Na2CO3 = = = nyora Na2SO3 + CO2 + H2O
2 nahso3 = = delta = = Na2SO3 + H2O + SO2 nyora
2. Reducibility:
3 na2so3 hno3 + 2 + 2 = = = = = 3 na2so4 kwete kunyora + H2O
2Na2SO3+O2====2Na2SO4
3. Kupisa:
4 na2so3 = = delta = = Na2S + 3 na2so4
4. Oxidation:
Na2SO3 + 3 h2s = = = = 3 s kuruboshwe + Na2S + 3 h2o [1]
Kugadzirira kwerabhoritari
Iyo sodium carbonate solution inopisa kusvika ku40 ℃ uye yakazara nesarufa dioxide, ipapo iyo yakafanana yesodium carbonate solution inowedzerwa, uye mhinduro yacho inonatswa pasi pemamiriro ekudzivisa kusangana nemhepo.

Risk Overview
Njodzi dzehutano: kumaziso, ganda, mucous membrane kutsamwa.
Njodzi dzezvakatipoteredza: njodzi kune zvakatipoteredza, inogona kukonzera kusvibiswa kumitumbi yemvura.
Kuputika njodzi: chigadzirwa hachipisi uye chinotsamwisa.
Matanho ekubatsira kwekutanga
Kubata ganda: bvisa zvipfeko zvine utachiona uye wogeza nemvura yakawanda inoyerera.
Kubata maziso: Simudza maziso uye wogeza nemvura inoyerera kana saline.Enda kuna chiremba.
Kufema: kure nechiitiko kuenda kumhepo yakachena.Ipa oxygen kana uchinetseka kufema.Enda kuna chiremba.
Kudya: inwa mvura inodziya inokwana kurutsa.Enda kuna chiremba.
Zviyero zvekudzivirira moto
Hunhu hune ngozi: hapana kupisa kwakakosha uye kuputika maitiro.Kuora kwepamusoro kwemafuta kunoburitsa utsi hwesarufidhi ine muchetura.
Zvinokuvadza kupisa chigadzirwa: Sulphide.
Nzira yekudzima moto: vashandi vemoto vanofanira kupfeka moto wakakwana - zvipfeko zvinodzivirira moto, kudzivirira moto mukati memhepo.
Emergency mhinduro kune leakage
Emergency treatment: iparadzanise nzvimbo yakasvibiswa yekudonha uye kurambidza kupinda.Inokurudzirwa kuti vashandi vekukurumidzira vapfeke masikisi eguruva (chifukidziro chakazara) uye masutu egasi.Dzivisa guruva, kunyatsotsvaira, kuisa mumabhegi uye kuendesa kunzvimbo yakachengeteka.Inogonawo kushambidzwa nemvura yakawanda uye yakasvibiswa mumvura yakasvibiswa.Kana pane inogona kuvhara yakawanda, shandisa pepa repurasitiki uye recycle leaka. kutambisa nzvimbo yekurasa.
Operation kuraswa uye kuchengetedza
Operation precautions: airtight operation, kusimbisa kufefetedza.Vashandi vanofanira kunge vakanyatsodzidziswa uye vanyatsotevedzera mashandisiro ekuita.Vashandi vanokurudzirwa kupfeka masiki eguruva ega ega, kupfeka magirazi ekudzivirira emakemikari, kupfeka mahovhorosi anodzivirira huturu, uye kupfeka magirovhosi erabha.Nzvenga guruva.Dzivisa kusangana neacids.Kubata zvinokuvadza.geakamp midziyo yekukurumidzira kudzivirira njodzi. chengetedza zvinhu zvinokuvadza.
Chengetedzo pakuchengetedza: Chengetedza munzvimbo inotonhorera, ine mhepo inotonhorera. Chengetedza kure nemoto nekupisa.Inofanira kupatsanurwa kubva kune acid uye imwe chengetedzo, usasanganise chengetedzo.Haugare kwenguva refu.Nzvimbo yekuchengetera ichapihwa zvinhu zvakakodzera kuchengetedza kuvuza.
Bata kutonga / chengetedzo yako pachako
Kudzora kweinjiniya: nzira yekugadzira yakavharwa, uye kufefetera kunosimbiswa.
Kudzivirirwa kwechirongwa chekufema: kana guruva remumhepo richidarika mwero, unofanirwa kupfeka guruva rekuzvidzivirira refirita mask.Muchiitiko chekununurwa kwekukurumidzira kana kubuda, mweya wekufema unofanirwa kupfekwa.
Dziviriro yeziso: pfeka magirazi ekuchengetedza makemikari.
Dziviriro yemuviri: pfeka anti-chepfu permeation yebasa zvipfeko.
Kudzivirirwa kwemaoko: pfeka magirovhosi erabha.
Kumwe kudzivirirwa: chinja mbatya dzebasa nenguva.Ramba uine hutsanana hwakanaka.
