Sulfurousʻakika. Nine waiwai,? Iecaianoaaiiie

Sulphurousʻakika - mea he lolelua ka'okanikaʻole dibasicʻakika o meakino ikaika. Fragile i huiia ua ike wale i loko o koʻana koko pāʻoihana ma ka lehulehu o ole aku mamua o eono hapahaneri. Ma ka ho'āʻo 'ana e kaʻawale maemae sulfurousʻakika, ia decomposes i ka sulfur dioxide i (SO2) a me ka wai (H2O). No ka laʻana, ka wā paku ole ia i sulfuricʻakika (H2SO4) i kiaʻana i kāna palapala i loko o paʻakai sulfite (Na2SO3) i pānaʻi no sulfurousʻakika oku u ka sulfur'okesaside (SO2). Eia mea keia naoh:

Na2SO3 (paʻakai sulfite) + H2SO4 (sulfuricʻakika) = Na2SO4 (paʻakai sulphate) + SO2 (sulfur dioxide i) + H2O (ka wai)

A pāʻoihana o sulfurousʻakika

Ma waho pūnaewele mea pono e hookaawale ia ea. I ole ia, sulfurousʻakika, lohi o ke kemu i oxygen (O2), lilo iho la sulfuric.

2H2SO3 (sulfurousʻakika) + O2 (oxygen) = 2H2SO4 (sulfuricʻakika)

sulfurousʻakika pāʻoihana e loa auaneʻiʻoukouʻala (ala reminiscent i koe ma hope o ke ahi ń), i ke alo o ka i hiki ke wehewehe ma ke alo o ka sulfur dioxide i (SO2), i ole chemically nakinakiia ka wai.

Nine waiwai o sulfurousʻakika

1. Sulfurousʻakika (haʻilula H2SO3) i ke hoʻohana like me ka hoemi hope paha oxidizing hope paha.

H2SO3 mea he maikai hoemi hope paha. Ua hiki ke hoʻohana 'noa o halogens loaa halides. No kekahi laʻana:

H2SO3 (sulfurousʻakika) + Cl2 (chlorine kinoea) + H2O (ka wai) = H2SO4 (sulfuricʻakika) + 2HCl (hydrochloricʻakika)

Akā, i ka AaOIeIOUIeXAOAaIN me ka ikaika hoemi i kēiaʻakika, e hana me ka oxidant. Lakou i mea hoike o ka naoh o sulfuricʻakika me ka hydrogen sulfide:

H2SO3 (sulfurousʻakika) + 2H2S (sulfide) = 3s (luaipele) + 3H2O (ka wai)

2. noonoo papa Nine Inch hui ano mau ano o ka paʻakai - sulfites (waena) a me hydrosulfites (ʻakika). Mau paʻakai e hoemi hope, e like me (H2SO3) sulfurousʻakika. I kā lākou oxidized ano paʻakai o sulfuricʻakika. Calcining sulfitesʻeleu metala sulfides a me sulfates i hana. Kēia ola auto-'okesaside naoh, ka hoʻoponopono-ho'ōla. No kekahi laʻana:

4Na2SO3 (paʻakai sulfite) = Na2S (paʻakai sulfide) + 3Na2SO4 (paʻakai sulufahate)

paʻakai a me ka potasiuma sulfite (Na2SO3 a me K2SO3) e hoʻohana i ka dyeing lole fabrics, ke hooheheeia ma ka loloʻa like pono me paʻi. Kalipuna hydrogen sulfite (Ca (HSO3) 2), a koe wale nō ma ka pāʻoihana, ua hoʻohana 'ia no ka aaioee i ka wahie i nā puke i loko o ka kūikawā sulfiteʻiʻo pepa. Mai ia laila, e pepa.

Ka hoʻohana a sulfurousʻakika

Sulfurousʻakika ua hoʻohana 'ia:

- no ka loloʻa hulu hipa, silika, ka lāʻauʻiʻo pepa, a me ka pepa 'ē aʻe like' ona mai i ke ku imua o ke loloʻa ka hoʻohana 'ana i ka ikaika oxidants (e laʻa me, chlorine);

- like me ka preservative a me ka antiseptic, e laʻa me, no ka pale i ka fermentation o ka hua liilii i loko o ka makaukau ana o ka pia paha, e pale aku fermentation ma ka waina barela;

- no ka malama ana o ka ai, e like me science ka lau a me ka hua;

- ma ka aaioee o ka laau? Inoaia o ka lāʻau i loko o ka sulfiteʻiʻo pepa, mai a loaa, alaila, o ka pepa. Ma keia hihia, he pāʻoihana o ke kalipuna sulfite (Ca (HSO3) 2), a hoike mai i ka lignin - he kūikawā waiwai e hoopaa ana i ka kelulose olona.

Sulfurousʻakika: e hoomakaukau ai no

Kēiaʻakika hiki ke loaa ma ka mea hoʻoheheʻeʻia sulfur dioxide i (SO2) i loko o ka wai (H2O). Oe Pono ka sulfuricʻakika i kiaʻana i kāna palapala (H2SO4), keleawe (cu) a me ka Tube. Ke algorithm mea:

1. E ninini Tube i kia sulphurousʻakika, a laila, e kau i kekahi'āpana o ke keleawe. Heat. ʻO kēia naoh ia lŘlŘ:

Cu (keleawe) + 2H2SO4 (sulfuricʻakika) = CuSO4 (sulphate luaipele) + SO2 (sulfur dioxide i) + H2O (ka wai)

2. Ka sulphurous kinoea kahawai e e kuhikuhi i loko o ka hue me ka wai. I ka wa e hoike mai i kekahi kumu o ia lŘlŘ he Nine Inch naoh i ka wai, a ua hanaʻia e like me ka hopena o sulfurousʻakika.

SO2 (sulfur dioxide i) + H2O (ka wai) = H2SO3

Penei, maalo ae la oia sulfur dioxide i ma ka wai, he mea hiki ke loaa mai i ka sulfurousʻakika. He kumukuai o ka noonoo ana o ka kinoea nāuki mai i ka naʻau o ka Hawaiian Airlines hiki i kona li nui, a me ka poho o kona'ōpū. Me ka lōʻihi-makahiki inhalation o kona hiki lilo o ka ike paka i. Leka me ke kinoea pono me ka palena mamao malama a me ka hoolohe.
