Hydrogen sulfide monko o tšoanang mahe bolileng, e tloaelehileng ho tsohle. Tlas'a maemo a tloaelehileng, ntho e ka boemo gaseous. Ho ea se nang 'mala, e hampe qhibilihang ka har'a ka metsi, e chefo. Ka kakaretso, ka likhato 20 Celsius sulfide 2,4 hydrogen tla qhala ka bophahamo ba modumo metsi a. Ka hydrogen sulfide metsi a senola hanyenyane asiti thepa dissociation moemeli o tsoela pele stepwise. Chefo sulfide hydrogen e kotsi esita le ka tekanyetso e nyenyane. Dikahare tsa moea ka bang liphesente tse 0,1 sulfide hydrogen isang shoele litho tsa setsi sa ho hema le ho lahleheloa ke akheha. Ka mohlala, tsomo tlhaho Pliniy Starshy ile a hlokahala ka la BC 79 la lilemo, ho ne ho sulfide hydrogen, e leng e thehoa nakong ea phatloha ea Vesuvius.

Lebaka la ketso tsa sulfide hydrogen chefo ka sebelisana lona lik'hemik'hale le haemoglobin maling. Tšepe tse nang le protheine ena e bopa e sulfide le sulfide hydrogen.

The lebetsoeng le lumelleha mahloriso ea sulfide hydrogen moeeng e nkoa e le 0,01 mg, / k. E le pheko ea sebelisoa inhalation oksijene e hloekileng kapa moea, eo ho eona sebopeho ho na le o fokolang palo ea chloride.

Ho sebetsa le sulfide hydrogen e hloka hore a latele melao ea tsamaiso itseng polokeho. Liteko tsohle malebana le sena lithethefatsi gaseous etsoa ka disebediswsa tiisitsoe le fume lik'habote.

Mekhoa ea ho hlahisa sulfide hydrogen

Ho fumana sulfide hydrogen ka laboratori joang? Ea atileng ka ho fetisisa ke sebelisana tsa hydrogen le sebabole le. Sena itsoara joang ka tsa lik'hemik'hale e bua ka komponeng e phethahatsoa ka fume Hood.

Ho feta moo, ba lokisetsa ho 'me mohlomong le sulfide hydrogen ka phapanyetsano pakeng tsa sulfide tiileng tšepe (2) le tharollo ea acid e sulfuric kapa hydrochloric. Ho fumana sephetho joalo, ka teko tube, ke ho lekaneng ho e nka likotoana tse seng kae tsa sebabole, ha e feta boholo ba erekisi ka. Ho ekelletsa moo, tube (halofo bophahamo ba modumo) o ile a phaella ka ho re le tharollo ea acid e, le mouoane tube, e koaloa. sesebediswa e behiloeng tlas'a Hood e, tube, ke halefile. Ba itšoara joang lik'hemik'hale e tsamaea le ho lokolloa ha bubble khase. Sena se nolofalletsa hore o bopa sulfide hydrogen ho fumana chelete ea lintho tse bonahalang ka ho lekaneng bakeng sa ho hlahlojoa ha lik'hemik'hale thepa ea eona.

Litsela life tse ling tse? Ka ho lokisetsa liteko tsa laboratori ea sulphide hydrogen e lumelloa ke itšoara metallic tšepe (tlas'a Hood a) le bonaletsang sebabole, lateloa ke itsoara joang ka tsa sulfide le asiti sulfuric.

Hydrogen sulfide a leka ho le oksijene moeeng, ho chesa 'mala o type genus. Tabeng ea lihlahisoa e feletseng combustion e itšoara joang ke dioxide e sebabole (4) le metsi. Fuoa hore sebōpi khase ke oxide e asiti, ka tharollo, ho bopa ba ho fokola acid e sulfurous, taka putsoa litmus pampiri e khubelu.

Tabeng ya tjhelete lekaneng tsa sulfide hydrogen thehoa bonaletsang sebabole. Tshebetso ena e nkoa ke lintho tse indasteri bakeng sa ho hlahisa sebabole ho tsoa sulfide hydrogen bo hloekileng.

Ka lik'hemik'hale ena a tsebahatsa le boitharabologelo babatsehang. Di bontšitse, ka mohlala, ka ho itšoara ka letsoai, halogens. E le hore ho khanna ka vitro itsoara joang ka tsela e tšoanang methapo teko le chlorine le bromine tšela sulfide tharollo, discoloration ile a hlokomela. E le sehlahisoa ba ikutloa ka tsela o ne a hlokomela hore ho thehoe oa sebabole bonaletsang.

Ha lik'hemik'hale itsoara joang ka tsa sulfide hydrogen ka metsi sebopeho sa hydronium ealogy H3O +.

Hydrogen sulfide ka theha mefuta e 'meli tsa metsoako: sulfides (mahareng letsoai) le hydrosulfides (asiti letsoai).

Ka lefatše alkali le alkaline tšepe sulfides ke metsoako colorless. Ka tšepe e boima (koporo, nikele, etella sechaba pele), ba batšo. Mankanese sulfide e na le 'mala o pinki. Tse ngata tsa letsoai ha qhala ka metsing.

Ya boleng itsoara joang ho sulfides fumana sebelisana le tharollo tsa koporo sulfate (2). Sehlahisoa sa sebelisana joalo e ntsho precipitate tsa sulfide koporo (2).
