Asiti Sulfurous. Lik'hemik'hale thepa, tlhahiso

Sulphurous acid e - ke sa tsitsang inorganic monohydrogenphosphate ba matla a mahareng. Boitjarong komponeng e tsejoa feela ka tharollo ea metsi ka ea mahloriso ya ho se lisente tse fetang tse tšeletseng ka. Ka boiteko ba ho itšehla asiti e hloekileng sulfurous, ho bola ho dioxide e sebabole (SO2) le metsi (H2O). Ka mohlala, ha a senola ho acid e sulfuric (H2SO4) foromo khobokellane ka sulfite sodium (Na2SO3) sebakeng sa sulfurous acid e lokolloa oxide e sebabole (SO2). Mona 's seo itsoara joang ka sena:

Na2SO3 (sodium sulfite) + H2SO4 (acid e sulfuric) = Na2SO4 (sodium sulphate) + SO2 (sebabole dioxide e) + H2O (metsi)

A tharollo ea acid e sulfurous

Nakong ea polokelo ke ho hlokahala hore ho qhelela ka thōko moeeng. Ho seng joalo, acid e sulfurous, butle-butle 'me le monya oksijene (O2), fetoloa sulfuric.

2H2SO3 (acid e sulfurous) + O2 (oksijene) = 2H2SO4 (acid e sulfuric)

sulfurous ditharollo acid e ke ikhethang haholo monko (monko o re hopotsang setseng ka mor'a tukang papali), ho ba teng ha e ka hlalosoa ka ho ba teng ha dioxide e sebabole (SO2), ha lik'hemik'hale tlamelletsoe metsi.

Lik'hemik'hale thepa ea acid e sulfurous

1. acid e Sulfurous (Mokgwa wa ho Nahana H2SO3) a ka sebelisoa e le moemeli fokotsa kapa moemeli oxidizing.

H2SO3 ke e ntle fokotsa moemeli. E ka sebediswa e sa lefelloeng ea halogens fumana halides. Mohlala:

H2SO3 (acid e sulfurous) + Cl2 (chloride le khase) + H2O (metsi) = H2SO4 (acid e sulfuric) + 2HCl (acid e hydrochloric)

Empa sebelisana le matla fokotsa acid e ena e tla sebetsa jwalo ka oxidant e. Mohlala ke ba itšoara joang ea acid e sulfuric le sulfide hydrogen:

H2SO3 (acid e sulfurous) + 2H2S (sulfide) = bo3 (sebabole) + 3H2O (metsi)

2. nkoa ka ikopanya le lik'hemik'hale komponeng e bopa tse peli tsa mofuta letsoai - sulfites (bohareng) le hydrosulfites (asiti). matsoai ana a fokotsa mahlahana a, hammoho le (H2SO3) acid e sulfurous. Ka mofuta oa bona oxidized letsoai ea acid e sulfuric. Calcining sulfites sulfides a sebetsang a tšepe le sulfates ba thehoa. Sena itsoara joang ka likoloi-ho kena moea, ba ikhopolang ho pholiso. Mohlala:

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

sodium le sulfite potassium (Na2SO3 le K2SO3) li sebelisoa daea li masela Textile, tšepe e soeufala hammoho le lifoto. sulfite k'halsiamo hydrogen (Ca (HSO3) 2), e teng feela tharollo, e sebelisoa bakeng sa ho sebetsana le patsi tse bonahalang e be sulfite makhasi ao e khethehileng. From ka nako eo etsa hore pampiri.

Tšebeliso ea acid e sulfurous

asiti Sulfurous e sebediswa:

- ho soeufala ulu, silika, makhasi ao lehong, pampiri le lintho tse ling tse tšoanang le se ke mamella soeufala sebelisa oxidants matla (mohlala, chloride le);

- ka e le ka senyeha le e sebolaya dikokwana-hloko, mohlala, bakeng sa ho thibela le belisoa ea lijo-thollo ka ba lokisetsa ho ea starch kapa ho thibela belisoa ka libarele veine;

- bakeng sa ho boloka lijo, tse kang meroho Canning le litholoana;

- ka e lokisa ya dita lehong la lehong ka makhasi ao sulfite, eo ka nako eo fumana pampiri. Tabeng ena, e le tharollo ea khalsiamo sulfite (Ca (HSO3) 2), e qhalana ho lignin - ntho e khethehileng hore e tlama likhoele selulose.

asiti Sulfurous: itokisa ya

asiti ena e ka fumanoa ka dissolving dioxide e sebabole (SO2) ka metsi (H2O). O hloka ho acid e sulfuric foromo khobokellane (H2SO4), koporo (cu) le phaephe e. The-tharabololo ke:

1. Ka hloko tšela tube, ka acid e khobokellane sulphurous ebe ho beha eteni ya koporo. Mocheso. Ba itšoara joang latelang le hlaha:

, Cu (koporo) + 2H2SO4 (acid e sulfuric) = CuSO4 (sulphate sebabole) + SO2 (sebabole dioxide e) + H2O (metsi)

2. sulphurous khase le molapo li lokela ho lebisoa be vial ka metsi. Ha ho qhalana karolo e 'ngoe e hlaha ba ikutloa ka tsela lik'hemik'hale ka metsi, e leng e thehoa ka lebaka la acid e sulfurous:

SO2 (sebabole dioxide e) + H2O (metsi) = H2SO3

Kahoo, ho fetisetsa dioxide e sebabole metsing, ho ka etsahala hore fumana acid e sulfurous. Ke habohlokoa ho ho nahana ka hore khase ea kea teneha lera la Lufthansa ka etsa hore ho ruruha lona, le tahlehelo ea takatso ea lijo. Ka nako e telele inhalation tahlehelo lona khoneha ea kelo-hloko. Iteanye le tlhoko ea khase ka hlokomela sohle se matleng a le tlhokomelo.
