Umahluko phakathi kweSodium Ferrocyanide kunye neSodium Cyanide

Kwindawo yekhemistri, Isodium Ferrocyanide kwaye Isodium cyanide Ziikhompawundi ezimbini ezithi, ngaphandle kokwabelana ngezinto ezithile zokuqamba, zineempawu ezahlukileyo. Ukuwuqonda lo mahluko kubalulekile, nokuba kukwizicelo zamashishini, kuphando lwezenzululwazi, okanye kuthathelwa ingqalelo ukhuseleko.

Ubume beMichiza kunye neeFomula

I-Sodium Ferroi-cyanide

I-Sodium ferrocyanide inefomula yemichiza ethi Na₄Fe(CN)₆. Iqulethe i-athomu yentsimbi ephakathi (Fe) elungelelaniswa ne-cyanide (CN) ligands ezintandathu, kunye ne-sodium ezine (Na⁺) ion ibhalansi intlawulo engalunganga ye-anion eyinkimbinkimbi [Fe(CN)₆]⁴⁻. Kwimo yayo ye-hydrated, ihlala ibonakala njenge-Na₄Fe(CN)₆·10H₂O. Olu lungelelaniso lunika i-sodium ferrocyanide ekhethekileyo yeekhemikhali kunye neempawu zomzimba.

Isodium cyanide

I-sodium cyanide, kunye nefomula ye-NaCN, yinto elula kakhulu ye-ionic. Iqukethe i-ion sodium (Na⁺) kunye ne-cyanide ion (CN⁻). I-cyanide ion luhlobo olusebenzayo kakhulu, olunegalelo elikhulu kwiimpawu zekhompawundi, ngakumbi ubutyhefu bayo.

Properties Properties

Kubonakala

I-sodium ferrocyanide ibonakala njengezinto eziqinileyo zekristale ezityheli. Umbala ophuzi luphawu lweanion ye-ferrocyanide. Okuchasene, sodium cyanide ibonakala njengeziqina ezimhlophe zekristale, ngokufuthi ikwimo yeegranules okanye umgubo.

Umzimba

I-sodium ferrocyanide iyanyibilika emanzini, kodwa ayinyibiliki etywaleni. Xa inyibilikiswa emanzini, iyahlukana ibe yi-ion ekhoyo, kuquka i-complex [Fe(CN)₆]⁴⁻ anion. Isodium cyanide, kwelinye icala, inyibilika kakhulu emanzini kwaye inyibilika kwezinye izinyibilikisi zepolar ezifana ne-ethanol. Iyakwazi ukwahlula emanzini ukukhulula i-ion zesodium kunye ne-cyanide ion, eyona nto ibalulekileyo ekusebenzeni kwayo kunye netyhefu.

Amanqaku anyibilikayo kunye nokubilisa

I-sodium ferrocyanide ayinayo indawo yokunyibilika echazwe kakuhle ngokwengqiqo yesintu. Xa ishushu, iphelelwa ngamanzi emzimbeni. Ngokomzekelo, iqala ukulahlekelwa iimolekyuli zamanzi malunga ne-50 ° C, kwaye kwi-81.5 ° C, iba yi-anhydrous. Ukufudumeza okungaphezulu ukuya kwi-435 ° C kukhokelela ekuboleni kwayo. Isodium cyanide inendawo yokunyibilika eyi-564°C kunye neqondo lokubila elingu-1469°C. Ezi ndawo ziphezulu zokunyibilika kunye nokubilisa zibangelwa yi-ionic bonds eyomeleleyo kwikhompawundi.

I-Chemical Reactivity

Ukuphinda kusebenze ngeAcids

I-sodium ferrocyanide izinzile xa kukho i-dilute, i-acids engashushumbisi. Noko ke, xa ibekwe kwi-asidi ejiyileyo, ebilayo, inokubola ivelise igesi yehydrogen cyanide yasimahla. Umzekelo, kwindawo eneasidi eyomeleleyo, le ntshukumo ilandelayo inokwenzeka: Na₄Fe(CN)₆ + 6H₂SO₄ (igxininiswe, iyabilisa) → 6HCN + 2FeSO₄ + 3Na₂SO₄ + 6H₂O. I-sodium cyanide iyasebenza kakhulu kunye neeasidi. Kwaneeasidi ezibuthathaka zinokusabela ngayo ukuze zivelise igesi yehydrogen cyanide, enetyhefu kakhulu. Ukusabela ngolu hlobo lulandelayo: NaCN + HCl → NaCl + HCN↑. Oku kuphinda kusebenze kunye neeasidi kwenza Isodium cyanide into eyingozi kakhulu xa kukho izinto ezinobumuncu.

Iimpendulo ze-Oxidation kunye nokuNcitshiswa

I-Sodium ferrocyanide ingafakwa i-oxidized phantsi kweemeko ezithile. Xa kukho ii-oxidizing agents ezinamandla, ingaguqulwa ibe zii-iron(III) complexes ezifana ne-ferricyanide. Umzekelo, i-reaction ene-oxidant efanelekileyo ingaguqula i-[Fe(CN)₆]⁴⁻ ibe yi-[Fe(CN)₆]³⁻. I-Sodium cyanide nayo ingabandakanyeka kwii-oxidation reactions. Xa kukho i-oxygen kunye nee-catalysts ezithile, ingafakwa i-oxidized ibe zizinto ezingenabungozi kangako. Umzekelo, xa kukho i-hydrogen peroxide, i-reaction ingaba: NaCN + H₂O₂ → NaCNO + H₂O (xa i-hydrogen peroxide incinci). I-reaction engaphezulu nge-hydrogen peroxide engaphezulu inokuguqula i-sodium cyanate (NaCNO) ibe yi-sodium biICarboni-ate (NaHCO₃) kunye ne-ammonia (NH₃).

Ulwakhiwo oluntsonkothileyo

I-sodium ferrocyanide ngokwayo iyikhompawundi entsonkothileyo. Inokusabela ngakumbi kunye nezinye iiyoni zetsimbi ukwenza izakhiwo ezintsha zolungelelwaniso. Umzekelo, xa usabela nge-iron(III) iityuwa, yenza i-pigment enzulu-eblue eyaziwa ngokuba yiPrussian blue, kunye ne-chemical formula Fe₄[Fe(CN)₆]₃. I-sodium cyanide inokwenza ii-complexes kunye nee-ion ezahlukeneyo zetsimbi. Ekukhutshweni kwegolide kunye nesilivere, umzekelo, i-sodium cyanide isetyenziselwa ukwenza isinyithi esinyibilikayo - i-cyanide complexes. Igolide (Au) isabela ngesodium cyanide kubukho beoksijini ukwenza i-ion entsonkothileyo [Au(CN)₂]⁻: 4Au + 8NaCN + O₂ + 2H₂O → 4Na[Au(CN)₂] + 4NaOH.

Utyhefu

Isodium Ferrocyanide

Nangona iqulethe i-cyanide ligands, i-sodium ferrocyanide inetyhefu ephantsi. Umbutho wezeMpilo weHlabathi kunye noMbutho woKutya kunye noLimo unqume ukuba ukwamkelwa kwansuku zonke kwe-sodium ferrocyanide yi-0 - 0.025 mg / kg yesisindo somzimba. Isizathu sobutyhefu bayo obuphantsi kukuba i-cyanide ligands kwi-sodium ferrocyanide ibotshelelwe ngokuqinileyo kwi-athomu yentsimbi ephakathi kwi-anion eyinkimbinkimbi. Phantsi kweemeko eziqhelekileyo, ayikhuphi lula iiyoni zecyanide, ezizintlobo ezinetyhefu kakhulu. Nangona kunjalo, xa kukho iiasidi ezinamandla okanye phantsi kokukhanya kwe-ultraviolet, inokubola ukuvelisa igesi ye-hydrogen cyanide, enetyhefu kakhulu.

Isodium cyanide

I-sodium cyanide yenye yezona zinto zinetyhefu eyaziwayo. Iyingozi kakhulu ebantwini nasezilwanyaneni. Xa ifakwe, ifakwe, okanye ifakwe eluswini, i-sodium cyanide inokukhulula i-cyanide ion (CN⁻) emzimbeni. Ezi ion ze-cyanide zinokubophelela kwii-athom zentsimbi kwi-cytochrome c oxidase, i-enzyme ebandakanyeka ekuphefumlweni kweselula. Oku kubopha kuthintela umsebenzi we-enzyme, ukuthintela iiseli ekusebenziseni ioksijini ngokufanelekileyo, okukhokelela kwi-asphyxiation yeselula. Nokuba isixa esincinci, esinje nge-0.1 - 0.3 grams, sinokubulala abantu.
