Dab tsi yog Cov Khoom Siv Lub Cev ntawm Sodium Cyanide?

Dab tsi yog Cov Khoom Siv Lub Cev ntawm Sodium Cyanide? cyanide Cyanide zog No. 1 daim duab

sodium cyanide (NaCN) yog ib qho tshuaj sib xyaw ua ke uas tau ua rau muaj kev cuam tshuam loj heev vim nws cov tshuaj lom thiab kev siv hauv kev lag luam. To taub nws Lub cev lub cev yog ib qho tseem ceeb rau kev tuav, khaws cia, thiab kev xav txog kev nyab xeeb. Ntawm no yog lub ntsiab lub cev muaj zog ntawm Sodium cyanide:

  1. tsos: Sodium cyanide feem ntau tshwm li dawb, crystalline granules, hmoov, los yog lumps. Nyob rau hauv nws daim ntawv ntshiab, nws muaj ib tug huv si, tsis muaj xim zoo li thaum nyob rau hauv kev daws los yog raws li ib tug ntshiab crystal. Txawm li cas los xij, cov qauv coj mus muag tej zaum yuav tshwm sim me ntsis - dawb vim yog impurities.

  2. Cov ntxhiab tsw: Nws muaj faint, yam ntxwv almond - zoo li tsw. Tab sis nws yog ib qho tseem ceeb uas yuav tsum nco ntsoov tias tsis yog txhua tus tuaj yeem kuaj pom tus ntxhiab no. Lub peev xwm los hnov ​​​​tsw cyanide tebchaw yog kev txiav txim siab caj ces, nrog rau feem tseem ceeb ntawm cov pejxeem tsis tuaj yeem pom cov ntxhiab tsw. Tsis tas li ntawd, nyob rau hauv qhuav tej yam kev mob, Sodium Cyanide feem ntau tsis muaj ntxhiab tsw. Cov ntxhiab tsw yuav hnov ​​​​ntau dua thaum nws raug huab cua ntub lossis dej, vim nws tom qab ntawd hydrolyzes tso tawm hydrogen cyanide (HCN), uas muaj cov ntxhiab tsw zoo-paub almond.

  3. Melting thiab Boiling Points: Sodium cyanide muaj cov ntsiab lus siab melting ntawm kwv yees li 563.7 ° C (1046.7 ° F). Qhov no qhia tias muaj zog ionic bonds nyob rau hauv lub compound. Nws qhov kub kub yog nyob ib ncig ntawm 1496 ° C (2725 ° F). Cov ntsiab lus siab melting thiab boiling no yog ib yam ntawm ionic tebchaw, qhov twg muaj zog electrostatic zog ntawm attraction muaj nyob nruab nrab ntawm cov sodium cations (Na⁺) thiab cyanide anions (CN⁻).

  4. ceev: Qhov ceev ntawm sodium cyanide yog 1.595 g/cm³. Tus nqi ntom ntom no pab txiav txim siab tus nqi ntawm cov khoom hauv ib lub ntim, uas yog ib qho tseem ceeb rau kev lag luam kev siv thiab kev tuav cov txheej txheem.

  5. solubility: Sodium cyanide yog soluble hauv dej heev. Ntawm 20 ° C, kwv yees li 48 grams ntawm sodium cyanide tuaj yeem yaj hauv 100 milliliters dej. Raws li qhov kub thiab txias, nws solubility kuj nce. Piv txwv li, ntawm 34.7 ° C, txog 82 grams tuaj yeem yaj hauv 100 milliliters dej. Nws tseem yog me ntsis soluble hauv ethanol thiab soluble nyob rau hauv lwm cov polar solvents xws li ammonia. Nyob rau hauv dej, nws dissociates rau hauv sodium ions (Na⁺) thiab cyanide ions (CN⁻), uas yog lub luag hauj lwm rau ntau yam ntawm nws cov tshuaj thiab toxicological zog.

  6. Hygroscopicity: Sodium cyanide yog hygroscopic, txhais tau tias nws muaj lub siab nyiam nqus dej los ntawm huab cua. Thaum nws nqus dej, nws tuaj yeem tsim hydrates. Qee qhov xwm txheej, qhov no tuaj yeem ua rau caking lossis clumping ntawm cov khoom siv yog tias nws khaws cia rau hauv qhov chaw ntub dej. Cov cuab yeej no tseem muaj feem cuam tshuam rau nws qhov chaw cia, vim nws yuav tsum tau khaws cia rau hauv qhov chaw qhuav kom tswj tau nws txoj kev ncaj ncees thiab tiv thaiv qhov tsis xav tau.

  7. Refractive Index: Lub refractive index ntawm sodium cyanide yog kwv yees li 1.452. Lub refractive index yog ib qho kev ntsuas ntawm ntau npaum li cas lub teeb yog khoov thaum nws dhau los ntawm ib yam khoom. Cov cuab yeej no tuaj yeem siv rau hauv kev tshuaj ntsuam xyuas los txheeb xyuas thiab ua tus yam ntxwv ntawm sodium cyanide hauv qee qhov xwm txheej, tshwj xeeb tshaj yog ua ke nrog lwm cov khoom siv lub cev thiab tshuaj lom neeg.

Nyob rau hauv cov ntsiab lus, sodium cyanide lub cev muaj zog, xws li nws cov tsos, tsw, melting thiab boiling ntsiab lus, ceev, solubility, hygroscopicity, thiab refractive index, plays lub luag hauj lwm tseem ceeb nyob rau hauv nws kev lag luam siv thiab kev nyab xeeb cov txheej txheem. Muab nws cov tshuaj lom heev, kev paub txog cov khoom no yog qhov tseem ceeb rau cov neeg ua haujlwm nrog lossis nyob ib puag ncig qhov sib xyaw no.
