Yintoni ixabiso le-pH ye-sodium cyanide, kwaye yahluke njani kwi-sodium chloride?

I-Sodium cyanide (NaCN) yikhompawundi engaphiliyo ethe yatsala ingqalelo enkulu ngenxa yeempawu zayo ezikhethekileyo kunye nokusetyenziswa kwayo, ngakumbi kwimizi-mveliso yezemigodi kunye neekhemikhali. Le nto ingenambala ikristale, efana neswekile ngembonakalo, iyanyibilika kakhulu emanzini kwaye yaziwa ngokuba yingozi yayo enamandla. Ngokwahlukileyo koko, iSodium Chloride (NaCl), eyaziwa ngokuba yityuwa yetafile, yikhompawundi engeyiyo ityhefu edlala indima ebalulekileyo kwiinkqubo ezahlukeneyo zebhayoloji kunye nezemizi-mveliso. Eli nqaku lijonga ngokusondeleyo i-pH yeSodium Cyanide , indlela eyahluke ngayo kwi-sodium chloride, kunye nemiphumo yokusetyenziswa kwayo.

Iimpawu zeMichiza kunye nexabiso le-pH

I-sodium cyanide yi-alkaline. Xa inyibilikisiwe emanzini, idlula kwi-hydrolysis ukuze yenze ii-hydroxide ions (OH⁻) kunye nee-ion ze-cyanide (CN⁻). I-pH yesisombululo se -sodium cyanide iyahluka ngokuxhomekeke kuxinzelelo lwe-NaCN kuyo. Ngokubanzi, izisombululo ze-sodium cyanide zine-pH engaphezulu kwe-7. nto leyo ebonisa ukuba ziyi-alkaline. Le mpawu ibalulekile kwiindlela ezahlukeneyo zokusetyenziswa, ngakumbi kwiinkqubo ezifuna uluhlu oluthile lwe-pH ukuze kusebenze kakuhle.

Ngokwahlukileyo, i-sodium chloride ayithathi hlangothi, kunye ne-pH ekufutshane ne-7 xa inyibilika emanzini. Lo mahluko usisiseko kwi-pH yenye yezinto eziphambili ezahlula i-sodium cyanide kwi-sodium chloride, echaphazela ukusetyenziswa kwazo kunye nokhuseleko.

Ukusetyenziswa kweSodium Cyanide

I-sodium cyanide yaziwa kakhulu ngendima yayo kwiMigodi yeGolide , apho isetyenziselwa ukukhupha igolide kwi-ores ngexesha lenkqubo ye-cyanidation. Le compound yenza i-complex ngegolide, ngaloo ndlela iyahlula kwezinye izimbiwa. Le ndlela isebenza kakhulu kwaye yamkelwe ngokubanzi kushishino lwemigodi. Ukongeza ekukhupheni igolide, i-sodium cyanide ikwasetyenziswa ekukhupheni isilivere nakwiinkqubo ezahlukeneyo ze-Electroplating , apho isebenza njengomthombo wee-ion ze-cyanide, inceda ukubekwa kweesinyithi phezu komhlaba.

Ukongeza kwizicelo zemigodi, i-sodium cyanide isetyenziswa kwi- Organic Synthesis nakwimveliso yamayeza. Yi-reagent ebalulekileyo ekuvelisweni kwee-organic nitrile compounds, ezibalulekileyo ekuvelisweni kweekhemikhali ezahlukeneyo kunye nezinto. Ukongeza, i-sodium cyanide isetyenziswa njenge-reagent kwi-analytical chemistry ukufumanisa ii-ions ezithile zesinyithi.

Nangona isetyenziswa ngeendlela ezahlukeneyo, i-sodium cyanide ibeka umngcipheko omkhulu ngenxa yokuba inetyhefu ephezulu. Le compound ayinavumba, kodwa xa ifakwa kwi-hydrolyze ikhupha inani elincinci le- Hydrogen Cyanide (HCN), igesi enobuthi kakhulu enevumba elifana nelee-almond ezikrakra. Le propati yenza i-sodium cyanide ibe yingozi kakhulu, njengoko ukuchatshazelwa yiyo kunokukhokelela kwimiphumo emibi kwimpilo, kubandakanya ukusilela kokuphefumla kunye nokufa.

Imiba yoKhuseleko kunye nobutyhefu

Ubuthi besodium cyanide ayinakujongelwa phantsi. Ihlelwa njengeyona nto iyingozi kakhulu kwaye inokubangela ukufa nakwixabiso elincinci. Ikhompawundi inokungena emzimbeni ngokuphefumla, ukungenwa okanye ukudibana nolusu, kubangele ukukhawuleza kweempawu ezinje ngentloko ebuhlungu, isiyezi, ukubhideka kwengqondo, kwaye kwiimeko ezimandundu, nokulahlekelwa zingqondo kunye nokufa. Kuqikelelwa ukuba i-dose ebulalayo ye-sodium cyanide kumntu omdala malunga ne-200-300 mg, eyenza enye yeekhemikhali eziyingozi kakhulu ezisetyenziswayo namhlanje.

Ngenxa yobume bayo obunobungozi, kukho imimiselo engqongqo malunga nokuphathwa, ukugcinwa kunye nokulahlwa kwe-sodium cyanide. Amashishini asebenzisa le khompawundi kufuneka aphumeze imigaqo yokhuseleko ebanzi ukukhusela abasebenzi kunye nokusingqongileyo. Oku kubandakanya ukusetyenziswa kwezixhobo zokukhusela zomntu (i-PPE), iinkqubo ezifanelekileyo zokungenisa umoya kunye nezicwangciso zokuphendula ngokukhawuleza kwimeko yokuvezwa ngengozi okanye ukuchithwa.

Ukuthelekisa neSodium Chloride

I-sodium chloride, ngakolunye uhlangothi, i-benign compound eyimfuneko kwimpilo yabantu kunye neenkqubo zezoshishino. Isetyenziswa ngokuqhelekileyo njengesiqholo sokutya kunye nesilondolozi kwaye idlala indima ebalulekileyo ekugcineni ibhalansi ye-electrolyte emzimbeni. Kwizicelo zoshishino, i-sodium chloride isetyenziselwa ukuveliswa kwe-chlorine kunye ne-caustic soda, kunye nakwiinkqubo zokunyanga kwamanzi.

Umehluko omkhulu phakathi kwe-sodium cyanide kunye ne-sodium chloride ibonisa ukubaluleka kokuqonda i-chemistry kunye nefuthe layo kukhuseleko kunye nempilo. I-sodium chloride ikhuselekile ukuyisebenzisa kwaye ineendlela ezahlukeneyo zokusetyenziswa okunenzuzo, ngelixa i-sodium cyanide ibonisa imingcipheko ebalulekileyo kwaye idinga ukulawulwa ngokucophelela kunye nokulawulwa.

 ukuququmbela

Isodium cyanide yikhompawundi enamandla kwaye eguquguqukayo enezicelo ezibalulekileyo kwimigodi yegolide, i-organic synthesis, kunye ne-electroplating. Nangona kunjalo, ubuthi bayo obuphezulu kunye neengozi ezinokubakho zifuna amanyathelo angqongqo okhuseleko kunye nemimiselo. Ukuqonda i-pH kunye nekhemikhali yesodium cyanide, kunye nendlela eyahluke ngayo kwi-sodium chloride, kubalulekile kuye nabani na osebenza okanye ofunda ezi khompawundi. Njengoko amashishini aqhubeka exhomekeke kwi-sodium cyanide kwizicelo ezahlukeneyo, uphando oluqhubekayo kunye nokuqhubela phambili kokhuseleko kubalulekile ekunciphiseni iingozi ezinxulumene nale nto iyingozi.

Isishwankathelo, ngelixa i-sodium cyanide idlala indima ebalulekileyo kwiinkqubo ezahlukeneyo zoshishino, iingozi zayo azikwazi ukuhoywa. Ukwazisa kunye nemfundo malunga neempawu zayo, ukusetyenziswa, kunye namanyathelo okhuseleko kubalulekile ukuqinisekisa impilo yabantu kunye nokusingqongileyo.
