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

Sodium Cyanide (NaCN) yog ib hom tshuaj uas tau nyiam mloog vim nws muaj tshuaj lom thiab siv rau hauv kev lag luam. Kev nkag siab txog nws cov khoom siv lub cev yog qhov tseem ceeb rau kev tuav, khaws cia, thiab kev nyab xeeb. Nov yog cov khoom siv lub cev tseem ceeb ntawm Sodium cyanide :

1. Tsos : Sodium cyanide feem ntau zoo li dawb, crystalline granules, hmoov, lossis lumps. Hauv nws daim ntawv ntshiab, nws muaj qhov huv si, tsis muaj xim thaum nyob rau hauv cov kua lossis ua ib tug crystal meej. Txawm li cas los xij, cov qauv lag luam qee zaum yuav zoo li me ntsis tawm - dawb vim yog impurities.

2. Tsw Qab : Nws muaj ib qho tsw qab me ntsis zoo li txiv almond. Tab sis nws yog ib qho tseem ceeb uas yuav tsum nco ntsoov tias tsis yog txhua tus neeg tuaj yeem pom qhov tsw qab no. Lub peev xwm los hnov ​​​​​​cov tshuaj cyanide yog txiav txim siab los ntawm noob caj noob ces, nrog rau ib feem loj ntawm cov pej xeem tsis tuaj yeem pom qhov tsw qab. Tsis tas li ntawd, nyob rau hauv cov huab cua qhuav, Sodium Cyanide feem ntau tsis muaj ntxhiab. Cov ntxhiab tsw yuav pom tseeb dua thaum nws raug rau huab cua ntub lossis dej, vim nws tom qab ntawd hydrolyzes kom tso tawm hydrogen cyanide (HCN), uas muaj cov ntxhiab tsw almond paub zoo.

3. Cov Qhab Nia Yaj Thiab Kub : Sodium cyanide muaj qhov kub yaj siab txog li 563.7 °C (1046.7 °F). Qhov no qhia tau tias muaj cov ionic bonds muaj zog hauv cov tshuaj. Nws qhov kub npau yog li 1496 °C (2725 °F). Cov qhov kub yaj thiab kub npau no yog cov yam ntxwv ntawm cov tshuaj ionic, qhov twg muaj zog electrostatic ntawm kev nyiam nyob nruab nrab ntawm cov sodium cations (Na⁺) thiab cyanide anions (CN⁻).

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

5. Kev Yaj : Sodium cyanide yaj tau zoo heev hauv dej. Thaum 20 °C, kwv yees li 48 grams ntawm sodium cyanide tuaj yeem yaj rau hauv 100 milliliters dej. Thaum qhov kub nce ntxiv, nws qhov kev yaj kuj nce ntxiv. Piv txwv li, thaum 34.7 °C, kwv yees li 82 grams tuaj yeem yaj rau hauv 100 milliliters dej. Nws kuj yaj tau me ntsis hauv ethanol thiab yaj tau rau hauv lwm cov kuab tshuaj polar xws li ammonia. Hauv dej, nws dissociates rau hauv sodium ions (Na⁺) thiab cyanide ions (CN⁻), uas yog lub luag haujlwm rau ntau yam ntawm nws cov tshuaj lom neeg thiab cov khoom lom.

6. Kev Hygroscopicity : Sodium cyanide yog hygroscopic, txhais tau tias nws muaj ib qho kev nyiam nqus cov dej noo ntawm huab cua. Thaum nws nqus dej, nws tuaj yeem tsim cov hydrates. Hauv qee kis, qhov no tuaj yeem ua rau cov khoom khov kho ua caking lossis clumping yog tias nws khaws cia rau hauv qhov chaw noo noo. Cov khoom no kuj muaj feem cuam tshuam rau nws qhov kev khaws cia, vim nws yuav tsum tau khaws cia rau hauv qhov chaw qhuav kom tswj tau nws qhov kev ncaj ncees thiab tiv thaiv cov tshuaj tiv thaiv tsis xav tau.

7. Refractive Index : Tus refractive index ntawm sodium cyanide yog kwv yees li 1.452. Tus refractive index yog qhov ntsuas ntawm ntau npaum li cas lub teeb raug khoov thaum nws hla dhau ib yam khoom. Cov khoom no tuaj yeem siv rau hauv cov txheej txheem analytical los txheeb xyuas thiab piav qhia txog sodium cyanide hauv qee qhov xwm txheej, tshwj xeeb tshaj yog ua ke nrog lwm yam khoom siv lub cev thiab tshuaj.

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.
