Chii chinonzi pH kukosha kwesodium cyanide, uye yakasiyana sei nesodium chloride?

Sodium cyanide (NaCN) inorganic compound yakakwezva kutarisisa kune yakasarudzika zvivakwa uye mashandisirwo, kunyanya mumigodhi nemakemikari maindasitiri. Iyi crystalline substance isina ruvara, yakafanana neshuga pakuonekwa, inonyungudika mumvura uye inozivikanwa nokuda kwehupfu hwayo hwakasimba. Mukupesana ne, Sodium Chloride (NaCl), inowanzozivikanwa semunyu wetafura, isiri-chepfu musanganiswa inoita basa rakakosha mumhando dzakasiyana dzebiological uye maindasitiri maitiro. Ichi chinyorwa chinotarisa zvakanyanya pH ye Sodium Cyanide, kuti yakasiyana sei nesodium chloride, uye zvinorehwa nekushandiswa kwayo.

Kemikari zvivakwa uye pH kukosha

Sodium cyanide ine alkaline. Kana yanyungudutswa mumvura, inopinda hydrolysis kuumba hydroxide ions (OH⁻) uye cyanide ions (CN⁻). Iyo pH yea sodium cyanide mhinduro inosiyana zvichienderana nehuwandu hweNaCN mairi. Kazhinji, sodium cyanide solutions ine pH yakakura kudarika 7. zvichiratidza kuti dzine alkaline. Ichi chivakwa chakakosha mumashandisirwo akasiyana siyana, kunyanya mumatanho anoda chaiyo pH renji kuti iite zvakakwana.

Kusiyana neizvi, sodium chloride haina kwayakarerekera, ine pH iri pedyo ne7 kana yanyungudutswa mumvura. Uyu mutsauko wakakosha mupH ndechimwe chezvinhu zvakakosha zvinosiyanisa sodium cyanide kubva sodium chloride, inokanganisa mashandisiro avo uye kuchengeteka.

Kushandiswa kweSodium Cyanide

Sodium cyanide inonyanya kuzivikanwa nebasa rayo mu Ndarama Kuchera, iyo inoshandiswa kuburitsa goridhe kubva mumatombo panguva yecyanidation process. Mushonga wacho unoumba yakaoma negoridhe, nokudaro ichiiparadzanisa kubva kune mamwe maminera. Iyi nzira inoshanda zvakanyanya uye yakagamuchirwa zvakanyanya muindasitiri yezvicherwa. Pamusoro pekubviswa kwegoridhe, sodium cyanide inoshandiswawo mukubvisa sirivha uye zvakasiyana electroplating maitiro, kwaanoita sosi ye cyanide ions, kufambisa kuiswa kwesimbi panzvimbo.

Pamusoro pemigodhi yekushandisa, sodium cyanide inoshandiswa mu Organic Synthesis uye kugadzirwa kwemishonga. Iyo yakakosha reagent mukugadzira organic nitrile makomisheni, ayo akakosha pakugadzirwa kweakasiyana makemikari uye zvinhu. Mukuwedzera, sodium cyanide inoshandiswa se reagent mu analytical chemistry kuona mamwe maion simbi.

Pasinei nehuwandu hwekushandiswa kwayo, sodium cyanide inoisa njodzi huru nekuda kwehupfu hwayo. Mushonga wacho haunhuhwi, asi kana waitwa hydrolyzed unoburitsa mashoma e Hydrogen Cyanide (HCN), gasi rine muchetura zvikuru rine hwema hwakafanana nemaarumondi anovava. Ichi chivakwa chinoita sodium cyanide kunyanya kuve nengozi, sezvo kuratidzwa kwairi kunogona kutungamira kuhutano hwakakomba, kusanganisira kutadza kufema uye kufa.

Safety Issues uye Toxicity

Iyo huturu hwesodium cyanide haigone kurerutswa. Inorongwa sechinhu chine ngozi zvikuru uye chinogona kukonzera rufu kunyange muzvikamu zviduku. Komboni yacho inogona kupinda mumuviri kuburikidza nekufemerwa, kupinza kana kubata ganda, zvichikonzera kukurumidza kutanga kwezviratidzo zvakaita sekutemwa nemusoro, dzungu, kuvhiringika kwepfungwa, uye muzviitiko zvakanyanya, kunyangwe kurasikirwa nekuziva uye kufa. Inofungidzirwa kuti inouraya yesodium cyanide kumunhu mukuru inenge 200-300 mg, zvichiita kuti ive imwe yemakemikari ane ngozi zvikuru anoshandiswa nhasi.

Nekuda kwehunhu hwayo hune ngozi, pane mirau yakasimba ine chekuita nekubata, kuchengetedza uye kuraswa kwesodium cyanide. Maindasitiri anoshandisa komputa iyi anofanirwa kuita yakazara chengetedzo protocol kuchengetedza vashandi uye nharaunda. Izvi zvinosanganisira kushandiswa kwemidziyo yekuzvidzivirira nayo (PPE), masisitimu ekufema zvakanaka uye zvirongwa zvekupindura zvechimbichimbi muchiitiko chekufumurwa netsaona kana kurasika.

Kuenzanisa neSodium Chloride

Sodium chloride, kune rumwe rutivi, iine benign compound iyo yakakosha kune hutano hwevanhu uye maindasitiri maitiro. Inowanzoshandiswa sechinhu chinonhuwira chikafu uye chekuchengetedza uye inoita basa rakakosha mukuchengetedza chiyero che electrolyte mumuviri. Mumaindasitiri ekushandisa, sodium chloride inoshandiswa mukugadzirwa kweklorini uye caustic soda, pamwe nemaitiro ekurapa mvura.

Musiyano mukuru pakati pesodium cyanide uye sodium chloride unoratidza kukosha kwekunzwisisa kemikari uye kukanganisa kwayo pakuchengetedza uye hutano. Sodium chloride yakachengeteka kushandisa uye ine zvakasiyana-siyana zvekushandisa zvinobatsira, nepo sodium cyanide inopa njodzi dzakakura uye inoda kungwarira manejimendi uye kudzora.

 pakupedzisa

Sodium cyanide ikomboni ine simba uye inoshanda zvakasiyana-siyana ine zvakakosha mumigodhi yegoridhe, organic synthesis, uye electroplating. Nekudaro, huturu hwayo hwepamusoro uye njodzi dzinogona kuitika zvinoda matanho akasimba ekuchengetedza uye mirau. Kunzwisisa pH uye chemistry yesodium cyanide, pamwe nekusiyana kwayo nesodium chloride, kwakakosha kune chero munhu anoshanda kana kudzidza aya makomisheni. Sezvo maindasitiri achiramba achivimba nesodium cyanide kune akasiyana maapplication, kuenderera mberi kwekutsvaga uye kufambira mberi kwekuchengetedza kwakakosha kudzikamisa njodzi dzine chekuita nechinhu ichi chine njodzi.

Muchidimbu, nepo sodium cyanide inobata basa rakakosha mumhando dzakasiyana dzemaindasitiri, njodzi dzayo hadzigone kuregererwa. Kuziva uye dzidzo nezve zvivakwa zvayo, mashandisiro, uye nhanho dzekuchengetedza zvakakosha kuti uve nechokwadi chehutano hwevanhu uye nharaunda.
