Asiti Hydrobromic. Mekhoa ea ho ho lokisetsa, 'meleng le thepa lik'hemik'hale

asiti Hydrobromic (eo hape a bitsoang lethal gene hydrogen) - ke komponeng inorganic tsa hydrogen (H) le bromine (BR). Ke khase colorless, eo e bopa e moholi o teteaneng moeeng le mongobo.

ke mekgwa ya fumana lethal gene hydrogen seo

Ka lebaka la ho isa tekanyong e phahameng ea acid e oxidizability bromovodoronoy, liphello tsa eona tse ka sa fumanehe ka acid e khobokellane sulfuric ho bromides a alkali tšepe. Ba itšoara joang latelang le hlaha:

2KBr (potassium lethal gene) + 2N2SO4 (acid e sulfuric) = K2SO4 (potassium sulfate) + SO2 (oxide e sebabole) + Br2 (bromine molek'hule) + 2H2O (metsi)

1. Ka acid indasteri fumana tse kang hydrobromic, etsoang ke ba ikutloa ka tsela eo ka eona likarolo constituent itšoara joang. Ka mohlala, re nahana ka ntho e ka fumanoa ka tsela e latelang:

H2 (hydrogen molek'hule) + Br2 (bromine molek'hule) = 2HBr (acid e hydrobromic)

itšoara joang Sena ke khoneha ho ya mocheso oa likhato tse 200 ho tse 400.

2. Hape, hoa khoneha ho fumana acid e hydrobromic ka vitro le ka litsela tse ngata.

- ka hydrolysis pentabromide kapa phosphorus tribromide:

PBr3 (tribromide) + 3H2O (limolek'hule metsi tse tharo) = H3PO3 (phosphoric acid) + 3HBr (acid e hydrobromic, lik'hemik'hale moralo)
PBr5 (pentabromide) + 4H2O (limolek'hule metsi a mane) = H3PO4 (phosphoric acid) + 5HBr (lethal gene hydrogen)

- ka phokotso ea bromine:

3Br2 (limolek'hule tse tharo bromine) + S (sebabole) + 4H2O (metsi) = (itšoara joang ka etsahala ka mocheso oa likhato 100-150) H2SO4 (acid e sulfuric) + 6HBr (lethal gene hydrogen)
3Br2 (limolek'hule tse tharo bromine) + KNO2 (potassium nitrite) + 4H2O (metsi) = KNO3 (nitrate potassium) + 2HBr (lethal gene hydrogen)

- displacing bolela ka acid e hlapolla tloha bromides a alkali tšepe:

Ingbr (potassium lethal gene) + H2SO4 (acid e sulfuric) = KHSO4 (potassium hydrogensulfate) + HBr (lokolloa ka khase)

3. E le ka sehlahisoa lethal gene hydrogen ka fumanoa ka tswakana tsa metsoako manyolo bromoproizvodnyh.

The thepa meleng lethal gene hydrogen:

1. hydrobromic acid e - e le khase ka ntle 'mala le monko o sa thabiseng le go utlwala. Ka matla smokes moeeng. E na le ho hanyetsa phahameng ho thempereichara e.

2. Ha e le hantle qhalwa ho ya ka H2O (metsi), le ho ethanol ya ho theha e electrolyte. The ea metsi HBr tharollo e bopa e azeotrope hore taba ka mocheso oa likhato tse 124. Ka litha e le nngwe le nngwe ya metsi qhalana ka bang ka litha e le nngwe halofo ea lethal gene hydrogen (ka 0 likhato).

3. Tsela ea Cooling e tharollo ea metsi ea lethal gene hydrogen bonaletsang hydrates e ka e ka lokisoa joaloka latelang: HBr * H2O, HBr * 2H2O, HBr * 4H2O.

4. Clean lethal gene liforomo kristale ea tsamaiso orthorhombic kristale, sebaka sehlopha F mmm.

5. Ha e le mocheso oa likhato tse -66,8 fetoha mokelikeli, 'me ka - 87 likhato solidifies.

Lik'hemik'hale thepa ea lethal gene hydrogen:

1. hydrobromic liforomo acid e ka ho itšoara ka metsi ka acid e matla ke monobasic. itsoara joang ka ena ke e latelang:

HBr + H2O (metsi) = Br- (bromine anion) + H3O + (hydronium Ion)

2. lintho tse bonahalang Sena ke manganga ho thempereichara e phahameng, leha ho le joalo, ka 1000 likhato ka bang 0.5% ea limolek'hule le bohle bao e leng bole:

2HBr (hydrobromic acid) = H2 (molek'hule hydrogen) + Br2 (bromine molek'hule)

3. nkoa ho ikopanya le komponeng lik'hemik'hale a leka ho le mefuta e fapaneng ya tšepe hammoho le makalana a bona 'me oxides. Mehlala a itšoare:

2HBr + MG (magnesium) = MgBr2 (magnesium lethal gene) + H2 (lokolloa ka khase)
2HBr + Cao (khalsiamo oxide e) = CaBr2 (khalsiamo lethal gene) + H2O (metsi)
HBr + NaOH (sodium hydroxide) = NaBr (sodium lethal gene) + H2O (metsi)

4. lethal gene ke e boetse e le moemeli fokotsa. E oxidized moeeng butle. Ka lebaka lena, ditharollo lona ea metsi ka mor'a nakoana pentoa ka sootho. Ba itšoara joang le tla ba e joalo:

4HBr (acid e hydrobromic) + O2 (oksijene molek'hule) = 2Br2 (bromine molek'hule) + 2H2O (metsi)

kopo

Lethal gene e sebediswa ho bopa (tswakana) ya derivatives tse fapa-fapaneng tse phelang bromine le bakeng sa ba lokisetsa ho ea bromides tse fapa-fapaneng tsa tšepe. Le ea bohlokoa ho khetheha ke tsa silevera tse lethal gene 'nile ha sebelisoa ka ho hlahisa thepa filimi ea lifoto.
