Ukuveliswa emanzini, iimpahla zazo, ukusetyenziswa

Kweli nqaku siza kujonga ekufumaneni nesulfure hydrogen sulphide. Uqwalaselo olubukhali iimpawu zomzimba eekhemikhali kweziyobisi.

isakhiwo

Ukuze uhlaziye ukwamkelwa eziphambili emanzini, kubalulekile ukufumana phandle i iimpawu lwesakhiwo yayo. Njengenxalenye osisiqu iqulethe sulphur atom enye hydrogen ezimbini. Yokuba non-ngesinyithi, ngoko phakathi izinto kwakhiwa iimbophelelo covalent ezibandayo. Isakhiwo emboxo ngayo emanzini hydrogen. Yenza engile 92 degrees phakathi isalfure hydrogen, nto leyo incinane kancinane emanzini.

iipropati ngokomzimba

Emanzini iphunga efana amaqanda ezibolileyo, liqhelekile bonke. Phantsi kweemeko eziqhelekileyo, iyeza le sikarhulumente sukube. Kuye akukho umbala, ayiqondakali enyibilikayo emanzini, eziyityhefu. Kwi-avareji, ngama-20 Celsius 2.4 emanzini inyibilikise umthamo wamanzi. Xa hydrogen amanzi emanzini kutyhilwa luncinane asidi iipropati arhente dissociation aqhubeke stepwise. Enetyhefu emanzini kuyingozi nokuba ngeedosi ezincinane. Content lomoya nama-0.1 ekhulwini emanzini kukhokelela ukushwabana iziko nokuphefumla kulahleka sezingqondweni. Hi xikombiso, le semvelo edume Pliniy Starshy wafa BC 79 leminyaka, hydrogen emanzini, nto leyo luqokelelane ngexesha kuqhuma ntshava.

Isizathu sokuba inyathelo emanzini eziyityhefu intsebenziswano yayo ikhemikhali ngehemoglobin egazini. Iron equlethwe kule iproteni eyenza ngayo emanzini kunye emanzini.

Le xi iphezulu avumelekile emanzini emoyeni uthathwa ukuba 0,01 mg / l. Njengoko alikaziwa kusetyenziswa inhalation ioksijini ecocekileyo okanye umoya, apho isakhiwo kukho isixa kancane chlorine.

Ukusebenza kunye emanzini hydrogen kufuna ukungqinelana nemigaqo ethile yokhuseleko. Onke amalinge ngale into sukube eyenziwa kwizixhobo itywiniweyo kunye iikhabhathi yimisi.

Iindlela zokuvelisa emanzini

Yintoni ngenyameko emanzini hydrogen kwilebhu? Lowo iqhelekileyo impefumlelwano hydrogen kunye nesalfure. Le yokusabela chemical ibhekisa yikhompawundi into eyenziwa kwindawo hood yimisi.

Ngaphezu koko, ukulungiswa kunye mhlawumbi emanzini hydrogen ngokutshintshiselana phakathi emanzini eziqinileyo yentsimbi (2) kunye nesisombululo acid sulphuric okanye zehydrochloric. Ukuze ufumane zawo, kuvavanyo ithumbu ngokwaneleyo ukuba iinkuni ezimbalwa isalfure, ayidluli ubungakanani-ertyisi. Ngaphezu koko, ityhubhu (umqulu isiqingatha) Kongezelelwa isisombululo asidi, ityhubhu Umphunga ivaliwe. Le fowuni ibekwe phantsi ukwesona, ithumbu itshiswa. Indlela abasabela imichiza ihamba ukukhutshwa egesi. Oku kukuvumela ukuba ukudala emanzini ukufumana isixa izinto ezaneleyo ukuze kuqwalaselwe iimpahla zazo chemical.

Zeziphi ezinye iindlela? Xa kulungiselelwa kwilebhu hydrogen sulphide uvunyelwe ngokuhlanganisa ebuntsimbi yentsimbi (phantsi hood) kunye isalfure crystalline, kulandelwe indlela emanzini kunye sulphuric acid.

iipropati chemical

Emanzini idityaniswe oksijini emoyeni, lona livutha umbala oluhlaza. Kwimeko epheleleyo iimveliso yokutsha reaction zezi sulphur dioxide (4) kunye namanzi. Sisazi ukuba irhasi ziko i oxide asidi, kwi isisombululo, yenza ababuthakathaka kabi acid, imibala blue iphepha litmus ebomvu.

Kwimeko izixa elingonelanga emanzini crystalline kwakhiwa nesalfure. Le nkqubo kuthathwa inkqubo yezoshishino ukuvelisa nesulfure emanzini ecocekileyo.

Kule chemical ezichongiweyo kunye nokomelela kakhulu. Siboniswa, umzekelo, ngokuthi zakudibana iityuwa, halogens. Ukuze baqhube in vitro indlela efanayo xa ityhubhu yovavanyo chlorine kunye bromine obuthululwayo isisombululo emanzini, umbala uyalandelwa. Njengoko imveliso basabela kwabonwa ukuyilwa sulphur crystalline.

Xa imichiza indlela emanzini ngamanzi ekumisweni hydronium zesiqinisekiso H3O +.

Emanzini uyakwazi ukwenza intlobo ezimbini iikhompawundi: sulfides (ityuwa medium) kunye hydrosulfides (ityuwa asidi).

Xa umhlaba kwealkali obrak sulfides etyhidiweyo iikhompawundi enemibala. Xa enzima (nobhedu, nickel, ilothe), elimnyama. emanzini manganese inombala epinki. Abaninzi ityuwa musa ukuluhlakaza emanzini.

asabela esemgangathweni ukuze sulfides ukufumana intsebenziswano isisombululo sulfate zobhedu (2). Imveliso ye intsebenziswano enjalo ke kwenze abamnyama emanzini yobhedu (2).

isiphelo

Kwindalo, le nto kweli imithombo nezimbiwa, iigesi mlilo. Le ephindeneyo yimveliso ukubola zezityalo nezilwanyana eziphilayo, oko eyahlula ivumba uphawu emanzini. sulfides Natural efumaneka kulwakhiwo zesinyithi ezinqabileyo kwi yokunyibilikisa isinyithi kubo kufumana izinto ezifanelekileyo. Kubalulekile ukukhumbula ukuba emanzini hydrogen into enamandla enetyhefu.
