Iipropati zeMichiza kunye nezicelo zoMfuniselo zeSodium Cyanide

I-sodium cyanide yi-inorganic compound eneempawu zeekhemikhali ezizodwa kwaye isetyenziswa ngokubanzi kwiilabhoratri kunye nemveliso yemizi-mveliso. Eli nqaku liza kuphonononga iimpawu zeekhemikhali ze Isodium cyanide kunye nendima yayo kwizicelo zovavanyo.

Properties Properties

I-sodium cyanide yikristale emhlophe, ehlala ikhona kwifomu eqinileyo. Izinzile kwiqondo lobushushu begumbi, kodwa phantsi kweemeko zokufudumeza okanye ukufuma okuphezulu, ibola ibe yi-hydrocyanic acid kunye ne-sodium hydroxide. Ifomula yayo yeekhemikhali yi-NaCN, kwaye ubunzima bayo be-molar yi-49.01 g / mol.

Iimpawu zeMichiza

1. I-Alkalinity : I-sodium cyanide sisiseko esomeleleyo. Inganciphisa izisombululo ze-asidi kwaye ivelise i-hydrocyanic acid (HCN) emanzini:

I-NaCN + H₂O → HCN + NaOH

Oku kwenza i-sodium cyanide idlale indima ebalulekileyo kwiimpendulo ze-acid-base neutralization.

2. Iimpendulo zeCyanide Ion : Umsebenzi ophambili wekhemikhali yesodium cyanide unxulumene neCyanide Ion (CN⁻). Le ion inokuthatha inxaxheba kwiimpendulo ezininzi, kubandakanya iimpendulo zesilivere, iimpendulo zekopolo, kunye ne-metal gilding. Umzekelo, ukusabela ngee-ion zesilivere (Ag⁺) kuya kwenza i-cyanide yesilivere enokuwela (AgCN).

3. Ubuthi : Zombini i-sodium cyanide kunye nesisombululo sayo samanzi ziyingozi kakhulu kuba i-cyanide ion inokubopha kwi-iron ions kwiiseli, iphazamise inkqubo yokuphefumla kweeseli. Oku kwenza i-sodium cyanide ibaluleke kakhulu kuphando lwe-toxicology.

Ukusetyenziswa koMfuniselo

1. Ukucubungula iMetal : I-sodium cyanide isetyenziswa kwi- Metal Processing yokucoca nge -Electroplating kunye nokususa ii-oxides zomphezulu. Ingasetyenziselwa ukucoca nge-electroplate izinyithi ezixabisekileyo ezifana negolide nesilivere phezu kwezinye izinto.

2. I-Analytical Chemistry : I-sodium cyanide isetyenziswa rhoqo kwi- Analytical Chemistry , ingakumbi kuhlalutyo lweetyuwa zesilivere. Inokunceda ekufumaneni ubukho besilivere, ubhedu, kunye nezinye ii-ion zesinyithi.

3. Ukwenziwa kwezinto eziphilayo : I-sodium cyanide isetyenziswa njengesiseko okanye i-catalyst kwi- Organic Synthesis . Ingabandakanyeka kwiimpendulo ezahlukeneyo, ezifana ne-Ullmann reaction kunye nokwenziwa kwee-Grignard reagents.

4. Uphando lweToxicology : Ngenxa yobuthi bayo, i-sodium cyanide isetyenziswa kuphando lweToxicology ukufunda indlela esebenza ngayo iityhefu kunye neendlela zokunyanga ubuthi.

Kufuneka kuqatshelwe ukuba ukusetyenziswa kwe-sodium cyanide kufuneka kulandele iinkqubo zokhuseleko, kwaye ubuthi bayo kufuneka balawulwe ngokungqongqo. Kwiindawo zebhubhoratri kunye nezoshishino, amanyathelo afanelekileyo okhuseleko kufuneka athathwe ukukhusela ukudibanisa kunye nokuvuza. Ukongezelela, ukusetyenziswa ngokusemthethweni kunye nokulahlwa kwe-sodium cyanide kufuneka kuhambelane nemithetho efanelekileyo kunye nemimiselo yokuqinisekisa ukhuseleko lokusingqongileyo kunye nempilo yabantu.
