Kabi acid. Iipropati Chemical, imveliso

Sulphurous acid - yinto ezingaphiliyo dibasic acid ezingazinzanga amandla medium of. compound ethe waziwa kuphela isisombululo zolwelo kwi iqela akukho cent ngaphezu ezintandathu nganye. Ezizama ikheswa kabi acid ecocekileyo, ibola ukuya sulphur dioxide (SO2) kunye namanzi (H2O). Ngokomzekelo, xa sisiva ukuba sulphuric acid (H2SO4) in ifomu kanzulu zibe sodium sulfite (Na2SO3) endaweni kabi acid akhululwe sulphur oxide (SO2). Nantsi into le ukusabela:

Na2SO3 (sodium sulfite) + H2SO4 (sulphuric acid) = Na2SO4 (sodium sulphate) + SO2 (sulphur dioxide) + H2O (amanzi)

A nesisombululo kabi acid

Ngexesha USB yimfuneko ukuba akhutshwe umoya. Kungenjalo, kabi acid, ngokucotha ukufunxa oxygen (O2), similise sulphuric.

2H2SO3 (kabi acid) + O2 (oksijini) = 2H2SO4 (sulphuric acid)

izisombululo acid kabi ezi iyinqaba Ivumba (ivumba kusikhumbuza eseleyo emva komdlalo evuthayo), ubukho apho kunokucaciswa phambi kwe-sulphur dioxide (SO2), kodwa iikhemikhali amanzi yento.

Iipropati lwemichiza kabi acid

1. kabi acid (Formula H2SO3) zingasetyenziswa njenge-arhente ukunciphisa okanye iarhente oxidizing.

H2SO3 i arhente elungileyo yokunciphisa. Ingasetyenziswa simahla halogens kufumana halides. Umzekelo:

H2SO3 (kabi acid) + Cl2 (igesi yeKhlorini) + H2O (amanzi) = H2SO4 (sulphuric acid) + 2HCl (zehydrochloric acid)

Kodwa ukusebenzisana enamandla ukunciphisa eli acid uya kwenza nje oxidant. Umzekelo zisabela kwe-sulphuric acid kunye emanzini:

H2SO3 (kabi acid) + 2H2S (emanzini) = abeBanga 3 (isalfure) + 3H2O (amanzi)

2. zezinto contact iikhemikhali compound Iifomu ezimbini iintlobo neetyuwa - sulfites (phakathi) kunye hydrosulfites (asidi). Ezi iityuwa sibenza agents, kwakunye (H2SO3) kabi acid. Kwabo oxidized uhlobo iityuwa kwe-sulphuric acid. Calcining sulfites sulfides zesinyithi esebenzayo kunye sulfates kwakheka. Le yokusabela auto-igcwala, self-ukuphiliswa. Umzekelo:

4Na2SO3 (sodium sulfite) = Na2S (sodium emanzini) + 3Na2SO4 (sodium sulfate)

Sodium kunye potassium sulfite (Na2SO3 kunye K2SO3) ezisetyenziswa yidayi amalaphu nemiqhaphu, isinyithi kwi sokukhanyisa kunye neefoto. Calcium hydrogen sulfite (Ca (HSO3) 2), apho ikhona kuphela isisombululo, zisetyenziswa nokuhlawulwa izinto iinkuni ibe sulfite ido- okhethekileyo. Ukususela ngoku ukwenza iphepha elitsha.

Ukusebenzisa kabi acid

Kabi acid:

- ngewulu aphuphe, isilika, emthini, amaphepha kunye nezinye izinto ezifana musa ukumelana mhlophe usebenzisa iioksidenti eyomeleleyo (umz, ichlorine);

- njenge ukubola kunye magciwane, umz, lokuthintela igwele zamabele ukulungiselela otashi okanye ukuthintela ibile kwi nemigqomo iwayini;

- ukuze kulondolozwe ukutya, ezifana nemifuno ukunkonkxwa neziqhamo;

- ekusetyenzweni chips iinkuni iinkuni kwi yintlama sulfite, ngoko ukufumana iphepha kuyo. Kulo mzekelo isisombululo ikhalsiyam sulfite (Ca (HSO3) 2), nto leyo eyibhangisa lignin - into ekhethekileyo oluhlanganisa imicu kwincindi.

Kabi acid: Ukulungiswa

Le asidi zingafumaneka ngokuthi dutywa sulphur dioxide (SO2) emanzini (H2O). Udinga i-sulphuric acid ifomu kanzulu (H2SO4), ubhedu (Cu) kunye ityhubhu. I algorithm:

1. Thela ityhubhu in sulphurous acid kanzulu koko ukubeka isiqwenga zezobhedu. Ubushushu. Indlela abasabela ilandelayo kwenzeka:

Cu (copper) + 2H2SO4 (sulphuric acid) = CuSO4 (sulphate isalfure) + SO2 (sulphur dioxide) + H2O (amanzi)

2. Lo mfula irhasi sulphurous kufuneka bangene igutyana ngamanzi. Xa iyachithakala inxenye kwenzeka yokusabela imichiza ngamanzi, oluthi luqokelelane ngenxa kabi acid:

SO2 (sulphur dioxide) + H2O (amanzi) = H2SO3

Ngenxa yoko, edlula sulphur dioxide emanzini, kungenzeka ukufumana i-kabi acid. Kubalulekile ukuqwalasela ukuba irhasi Iyandikruqula ingaphakathi yomoya kusenokubangela umtshiso yayo, kunye nelahleko onombilini. Nge inhalation ixesha elide yelahleko layo kunokwenzeka lokuqonda. Qhagamshelana ne imfuneko igesi kunye ngenyameko enkulu ingqalelo.
