Production na hydrogen sulfide, da kaddarorin, da yin amfani da

A wannan labarin, za mu duba a samun sulfur daga hydrogen sulphide. A kusa look at cikin jiki da kuma sinadaran Properties daga cikin abu.

tsarin

Domin bincika babban liyafar na hydrogen sulfide, shi wajibi ne don gano da siffofin da tsarin. Kamar yadda wani ɓangare na abu ya ƙunshi daya sulfur zarra da biyu hydrogen. Su ne wadanda ba karafa, don haka tsakanin abubuwa kafa covalent iyakacin duniya shaidu. A kusurwa tsarin da hydrogen sulfide. Yana Forms wani kwana na 92 digiri tsakanin sulfur da kuma hydrogen, wanda shi ne dan kadan karami fiye da a ruwa.

jiki Properties

Hydrogen sulfide wari kama rududdugaggu qwai, shi ne saba wa duk. Karkashin al'ada yanayi, abu ne a cikin gaseous jihar. Yana yana da wani launi, shi ne talauci mai narkewa a cikin ruwa, m. A kan talakawan, a 20 digiri Celsius 2.4 hydrogen sulfide zai narke a cikin ruwa girma. A hydrogen sulfide ruwa saukar kadan acidic Properties dissociation wakili fitowa stepwise. M hydrogen sulfide ne m har ma a kananan allurai. Abun ciki na iska kamar 0.1 bisa dari hydrogen sulfide take kaiwa zuwa inna na numfashi cibiyar da asarar sani. Alal misali, almara halittu Pliniy Starshy mutu a 79 arni na BC, shi ne hydrogen sulfide, wanda aka kafa a lokacin da shigowa na Vesuvius.

Dalilin da mataki na hydrogen sulfide guba a cikin sinadaran hulda da haemoglobin a cikin jini. Iron kunshe ne a cikin wannan sunadari Forms sulfide da hydrogen sulfide.

Matsakaicin canja maida hankali hydrogen sulfide a cikin iska da aka dauke su 0.01 MG / l. Kamar yadda wani maganin guba amfani da inhalation tsantsa oxygen ko iska, a cikin abin da tsarin akwai wani kadan adadin chlorine.

Aiki tare da hydrogen sulfide bukatar yarda da wasu aminci dokoki. All gwaje-gwajen a kan wannan gaseous abu kwashe a hatimce na'urorin da fume tukunya.

Hanyar samar da hydrogen sulfide

Abin da ake samun da hydrogen sulfide a cikin Lab? Mafi na kowa daya ne hulda da hydrogen da sulfur. Wannan sunadarai dauki tana nufin wani fili cewa yana da za'ayi a cikin wani fume kaho.

Bugu da ƙari, cikin shirye-shiryen da kuma yiwu da hydrogen sulfide a musayar tsakanin m baƙin ƙarfe sulfide (2) da kuma wani bayani da sulfuric ko hydrochloric acid. Don samun irin wannan a sakamakon, a cikin gwajin tube shi ne isa ya dauki 'yan guda na sulfur, ba ya wuce girman da wani fis. Bugu da ari, tube (rabin girma) ya kara da cewa cikin acid bayani, da tururi bututu da ake rufe. The na'urar da aka sanya karkashin kaho, da tube shi ne mai tsanani. A sinadaran dauki yana tare da saki da gas kumfa. Wannan ba ka damar haifar hydrogen sulfide kafin su sami adadin kayan ishe la'akari da ta sinadaran Properties.

Abin da sauran hanyoyi ne? A cikin dakin gwaje-gwaje shiri na hydrogen sulphide shi ne yarda da maida martani ƙarfe baƙin ƙarfe (a karkashin wani kaho) da crystalline sulfur, bi da dauki na sulfide da sulfuric acid.

sinadaran Properties

Hydrogen sulfide reacts tare da oxygen a cikin iska, shi konewa a bluish launi. A cikin hali na cikakken konewa dauki kayayyakin ne sulfur dioxide (4) da kuma ruwa. Ganin cewa makera gas ne acidic oxide, a cikin bayani, shi Forms wani rauni sulfurous acid, kala blue litmus takarda ja.

A hali na kasa yawa na hydrogen sulfide kafa crystalline sulfur. Wannan tsari yana dauke da wani m tsari ga samar da sulfur daga m hydrogen sulfide.

A wannan sinadaran gano da kuma m tsirar. Suna nuna, misali, ta hanyar maida martani da salts, halogens. Domin gudanar a vitro kama dauki a gwajin shambura tare da chlorine da bromine zuba sulfide bayani, discoloration aka kiyaye. Kamar yadda wani dauki samfurin da aka lura da samuwar crystalline sulfur.

Lokacin da sinadaran dauki na hydrogen sulfide da ruwa da samuwar hydronium cation H3O +.

Hydrogen sulfide iya samar da iri biyu mahadi: sulfides (matsakaici gishiri) da kuma hydrosulfides (acidic gishiri).

A Alkali da alkaline duniya karfe sulfides ne colorless mahadi. A nauyi karafa (tagulla, nickel, gubar), su ne baki. Manganese sulfide yana da wani ruwan hoda launi. Mutane da yawa na gishiri ba narke a cikin ruwa.

Ingantaccen dauki zuwa sulfides sami hulda da jan karfe sulfate bayani (2). A samfurin irin wannan hulda ne baki precipitate na jan sulfide (2).

ƙarshe

A yanayi, wannan abu ne a cikin ma'adinai marẽmari, volcanic gas. Wannan fili shi ne wani samfurin na lalata da shuka da dabbobi kwayoyin, shi ya bambanta da halayyar wari na hydrogen sulfide. Halitta sulfides samu a cikin abun da ke ciki na rare karafa a cikin metallurgy na su sami dace abubuwa. Yana da muhimmanci a tuna cewa hydrogen sulfide ne mai karfi da guba abu.
