Kemikari Zvivakwa uye Kuedza Mashandisirwo eSodium Cyanide

Sodium cyanide inorganic compound ine yakasarudzika makemikari zvimiro uye inoshandiswa zvakanyanya mumarabhoritari nekugadzirwa kwemaindasitiri. Ichi chinyorwa chichaongorora maitiro emakemikari e Sodium Cyanide uye basa rayo mukuedza kushandiswa.

Proper Properties

Sodium cyanide ikristaro chena, kazhinji iripo mune yakasimba fomu. Iyo inogadzikana pamhepo tembiricha, asi pasi pekudziya kana yakakwira - humidity mamiriro, inoora kuita hydrocyanic acid uye sodium hydroxide. Mushonga wayo wemakemikari ndeyeNaCN, uye uremu hwayo hunosvika 49.01 g/mol.

Chemical Zvivakwa

1. Alkalinity : Sodium cyanide ihwaro hwakasimba. Inogona kudzikamisa acidic solutions uye kugadzira hydrocyanic acid (HCN) mumvura:

NaCN + H₂O → HCN + NaOH

Izvi zvinoita kuti sodium cyanide iite basa rakakosha mukuita kweacid-base neutralization reactions.

2. Maitiro eCyanide Ion : Basa guru remakemikari resodium cyanide rine chekuita neCyanide Ion (CN⁻). Iyi ion inogona kutora chikamu mumaitiro akawanda, kusanganisira maitiro esirivha, maitiro emhangura, uye gilding yesimbi. Semuenzaniso, kusangana nemaion esirivha (Ag⁺) kunoumba silver cyanide (AgCN) inodonha.

3.Kukuvadzwa : Zvese sodium cyanide nemushonga wayo wemvura zvine chepfu yakawanda nekuti cyanide ion inogona kusunganidza kune iron ions mumasero, zvichikanganisa kufema kwemasero. Izvi zvinoita kuti sodium cyanide ive yakakosha mukutsvagisa kwetoxicology.

Experimental Applications

1. Kugadzira Simbi : Sodium cyanide inoshandiswa mukugadzira Simbi yeElectroplating nekubvisa ma oxides pamusoro. Inogona kushandiswa electroplate simbi dzinokosha dzakadai segoridhe nesirivha pamusoro pezvimwe zvinhu.

2. Analytical Chemistry : Sodium cyanide inowanzoshandiswa muAnalytical Chemistry , kunyanya mukuongorora sirivha munyu. Inogona kubatsira kuona kuvapo kwesirivha, mhangura, nedzimwe ions dzesimbi.

3. Organic Synthesis : Sodium cyanide inoshandiswa sehwaro kana catalyst muOrganic Synthesis . Inogona kutora chikamu muzviitiko zvakasiyana-siyana, zvakaita seUllmann reaction uye kugadzirwa kweGrignard reagents.

4. Tsvagiridzo yeToxicology : Nekuda kwechepfu yayo, sodium cyanide inoshandiswa mukutsvagisa kwetoxicology kudzidza mashandiro anoita chepfu uye nzira dzekurapa chepfu.

Zvinofanira kuonekwa kuti kushandiswa kwe sodium cyanide kunofanira kutevera nzira dzekuchengetedza, uye huturu hwayo hunofanira kunyatsodzorwa. Munzvimbo dzema laboratori uye maindasitiri, matanho akakodzera ekuchengetedza anofanirwa kutorwa kudzivirira kubata uye kubuda. Pamusoro pezvo, kushandiswa zviri pamutemo uye kuraswa kwesodium cyanide kunofanirwa kutevedzera mitemo nemirau yakakodzera kuve nechokwadi chekuchengetedza kwezvakatipoteredza uye hutano hwevanhu.
