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

Sodium cyanide (NaCN) chinhu chisina kugadzirwa chakakwezva vanhu vakawanda nekuda kwehunhu hwayo hwakasiyana uye mashandisirwo ayo, kunyanya mumaindasitiri emigodhi nemakemikari. Chinhu ichi chisina ruvara, chine chitarisiko chakafanana neshuga, chinonyunguduka mumvura uye chinozivikanwa nekukuvadza kwacho kwakasimba. Kusiyana neizvi, Sodium Chloride (NaCl), inozivikanwa semunyu wetafura, chinhu chisina chepfu chinoita basa rakakosha mumabasa akasiyana-siyana ehupenyu nemaindasitiri. Chinyorwa chino chinotarisa zvakanyanya pH yeSodium Cyanide , kuti yakasiyana sei nesodium chloride, uye zvazvinoreva pakushandiswa kwayo.

Kemikari zvivakwa uye pH kukosha

Sodium cyanide ine alkaline. Kana yanyungudutswa mumvura, inonyungudutswa kuita hydroxide ions (OH⁻) uye cyanide ions (CN⁻). pH ye sodium cyanide solution inosiyana zvichienderana nehuwandu hweNaCN mairi. Kazhinji, sodium cyanide solutions dzine pH inopfuura 7. zvichiratidza kuti dzine alkaline. Hunhu uhwu hwakakosha mukushandiswa kwakasiyana-siyana, kunyanya mumabasa anoda pH range chaiyo kuti ishande zvakanaka.

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 inozivikanwa zvikuru nebasa rayo muMigodhi yeGoridhe , uko inoshandiswa kuburitsa goridhe kubva mumatombo panguva yekuiswa kwecyanidation. Musanganiswa uyu unoumba goridhe, nokudaro uchiiparadzanisa nezvimwe zvicherwa. Nzira iyi inoshanda zvikuru uye yave ichishandiswa zvakanyanya muindasitiri yemigodhi. Kuwedzera pakubvisa goridhe, sodium cyanide inoshandiswawo mukubvisa sirivha uye maitiro akasiyana-siyana eElectroplating , uko inoshanda senzvimbo yekupa maion ecyanide, zvichiita kuti simbi dzirambe dzichiiswa pamusoro.

Pamusoro pekushandiswa kwekuchera, sodium cyanide inoshandiswa mukugadzirwa kweOrganic Synthesis uye mukugadzirwa kwemishonga. Inoshanda zvikuru mukugadzirwa kwemakemikari e organic nitrile, ayo akakosha pakugadzirwa kwemakemikari akasiyana-siyana nezvinhu. Pamusoro pezvo, sodium cyanide inoshandiswa se reagent mu analytical chemistry kuona mamwe ma ions esimbi.

Pasinei nekushandiswa kwayo kwakasiyana-siyana, sodium cyanide ine njodzi huru nekuda kwechepfu yayo yakawanda. Mushonga uyu hauna hwema, asi kana ukashandiswa hydrolyzed unoburitsa huwandu hushoma hweHydrogen Cyanide (HCN), gasi rine chepfu ine hwema hwakafanana nehwema hwema hwema. Izvi zvinoita kuti sodium cyanide ive nengozi zvikuru, sezvo kuiswa mairi kunogona kukonzera migumisiro yakaipa pahutano, 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.
