Tus nqi pH ntawm sodium cyanide yog dab tsi, thiab nws txawv ntawm sodium chloride li cas?

Sodium cyanide (NaCN) yog ib qho inorganic compound uas tau nyiam ntau xim rau nws cov khoom tshwj xeeb thiab kev siv, tshwj xeeb tshaj yog hauv kev lag luam mining thiab tshuaj lom neeg. Cov khoom tsis muaj xim crystalline, uas zoo li cov suab thaj hauv qhov tsos, yog soluble hauv dej thiab paub txog nws qhov muaj zog toxicity. Piv txwv li, Sodium Chloride (NaCl), feem ntau hu ua cov ntsev ntsev, yog cov tshuaj tsis muaj tshuaj lom uas ua lub luag haujlwm tseem ceeb hauv ntau yam txheej txheem lom neeg thiab kev lag luam. Kab lus no yuav siv sij hawm ze dua ntawm pH ntawm Sodium Cyanide, nws txawv li cas ntawm sodium chloride, thiab qhov cuam tshuam ntawm kev siv.

Chemical zog thiab pH nqi

Sodium cyanide yog alkaline. Thaum yaj hauv dej, nws nkag mus rau hydrolysis los tsim hydroxide ions (OH⁻) thiab cyanide ions (CN⁻). pH ntawm a sodium cyanide Kev daws nws txawv nyob ntawm qhov concentration ntawm NaCN hauv nws. Feem ntau, cov tshuaj sodium cyanide muaj pH ntau dua 7. qhia tias lawv yog alkaline. Cov cuab yeej no yog qhov tseem ceeb hauv ntau yam kev siv, tshwj xeeb tshaj yog nyob rau hauv cov txheej txheem uas yuav tsum tau muaj ib qho pH ntau yam rau kev ua haujlwm zoo.

Hauv qhov sib piv, sodium chloride yog nruab nrab, nrog pH ze rau 7 thaum yaj hauv dej. Qhov sib txawv hauv pH no yog ib qho tseem ceeb ntawm kev sib txawv ntawm sodium cyanide los ntawm sodium chloride, cuam tshuam rau lawv cov kev siv thiab kev nyab xeeb.

Kev siv Sodium Cyanide

Sodium cyanide feem ntau paub txog nws lub luag haujlwm hauv Kub Tsuas, qhov twg nws yog siv los rho tawm kub los ntawm ore thaum lub sij hawm cyanidation txheej txheem. Lub compound tsim ib tug complex nrog kub, yog li cais nws los ntawm lwm yam minerals. Txoj kev no zoo heev thiab tau siv dav hauv kev lag luam mining. Ntxiv nrog rau kev rho tawm kub, sodium cyanide kuj tseem siv rau hauv cov nyiaj rho tawm thiab ntau yam Electroplating cov txheej txheem, qhov twg nws ua raws li qhov chaw ntawm cyanide ions, ua kom yooj yim rau kev tso cov hlau rau ntawm qhov chaw.

Ntxiv nrog rau kev siv mining, sodium cyanide yog siv hauv Organic Synthesis thiab kev tsim tshuaj. Nws yog ib qho tseem ceeb reagent hauv kev tsim cov organic nitrile tebchaw, uas yog qhov tseem ceeb rau kev tsim khoom ntawm ntau yam tshuaj thiab cov ntaub ntawv. Tsis tas li ntawd, sodium cyanide yog siv los ua reagent hauv analytical chemistry txhawm rau txheeb xyuas qee yam hlau ions.

Txawm hais tias nws siv ntau yam, sodium cyanide ua rau muaj kev pheej hmoo loj vim nws cov tshuaj lom neeg siab. Lub compound tsis muaj ntxhiab, tab sis thaum hydrolyzed nws tso me me ntawm Hydrogen Cyanide hmoov (HCN), cov pa phem heev uas muaj ntxhiab tsw zoo ib yam li iab iab. Cov cuab yeej no ua rau sodium cyanide txaus ntshai tshwj xeeb, vim tias nws tuaj yeem ua rau muaj kev noj qab haus huv hnyav, suav nrog kev ua pa tsis ua haujlwm thiab tuag.

Teeb meem kev nyab xeeb thiab toxicity

Lub toxicity ntawm sodium cyanide tsis tuaj yeem kwv yees. Nws raug cais raws li cov khoom muaj kev phom sij heev thiab tuaj yeem ua rau tuag taus txawm tias me me. Cov tshuaj muaj peev xwm nkag mus rau hauv lub cev los ntawm kev nqus pa, noj lossis kev sib cuag ntawm daim tawv nqaij, ua rau cov tsos mob sai sai xws li mob taub hau, kiv taub hau, tsis meej pem, thiab mob hnyav, txawm tias tsis nco qab thiab tuag. Nws tau kwv yees tias qhov koob tshuaj tuag ntawm sodium cyanide rau tus neeg laus yog li 200-300 mg, ua rau nws yog ib qho tshuaj txaus ntshai tshaj plaws hauv kev siv niaj hnub no.

Vim nws qhov xwm txheej tsis zoo, muaj cov kev cai nruj heev txog kev tuav, khaws cia thiab pov tseg ntawm sodium cyanide. Kev lag luam uas siv qhov sib xyaw no yuav tsum ua kom tiav cov txheej txheem kev nyab xeeb los tiv thaiv cov neeg ua haujlwm thiab ib puag ncig. Qhov no suav nrog kev siv cov cuab yeej tiv thaiv tus kheej (PPE), cov tshuab ua pa kom raug thiab cov phiaj xwm teb xwm txheej kub ntxhov thaum muaj xwm txheej tshwm sim los yog nchuav.

Kev sib piv nrog Sodium Chloride

Sodium chloride, ntawm qhov tod tes, yog ib qho benign compound uas yog qhov tseem ceeb rau tib neeg kev noj qab haus huv thiab kev lag luam. Nws yog feem ntau siv los ua zaub mov flavoring thiab preservative thiab plays lub luag haujlwm tseem ceeb hauv kev tswj cov electrolyte hauv lub cev. Hauv cov ntawv thov kev lag luam, sodium chloride yog siv los tsim cov tshuaj chlorine thiab caustic soda, nrog rau cov txheej txheem kho dej.

Qhov sib txawv me ntsis ntawm sodium cyanide thiab sodium chloride qhia txog qhov tseem ceeb ntawm kev nkag siab txog chemistry thiab nws qhov cuam tshuam rau kev nyab xeeb thiab kev noj qab haus huv. Sodium chloride muaj kev nyab xeeb rau kev haus thiab muaj ntau yam kev siv tau zoo, thaum sodium cyanide nthuav tawm cov kev pheej hmoo tseem ceeb thiab yuav tsum tau ua tib zoo saib xyuas thiab tswj xyuas.
