Sodium cyanide (NaCN) ndi mankhwala omwe amagwiritsidwa ntchito kwambiri m'mafakitale komanso poizoni wambiri. Poganizira momwe thupi limakhalira kutentha (nthawi zambiri kumatanthawuza pafupifupi 20 - 25 ° C), Sodium cyanide alipo ngati cholimba.
Zinthu Zakuthupi Zosonyeza Dziko Lolimba
Melting Point ndi Boiling Point: Sodium cyanide imakhala ndi malo osungunuka kwambiri pafupifupi 563.7°C mpaka 564°C. Kuwira kwake ndikokwera kwambiri, pafupifupi 1496 ° C. Popeza kutentha kwa chipinda kumakhala pansi pa malo ake osungunuka, kumakhalabe mu mawonekedwe olimba a crystalline. Pamalo olimba, ma ion a sodium (Na⁺) ndi cyanide (CN⁻) amagwiridwa pamodzi mumtundu wa lattice ndi zomangira zolimba za ionic.
Maonekedwe: Nthawi zambiri, Sodium Cyanide amawoneka ngati zolimba zoyera za crystalline, zomwe zimathanso kusinthidwa kukhala ufa kapena mtanda wolimba. Maonekedwe owoneka bwinowa ndi mawonekedwe a chinthu cholimba kutentha kutentha.
Kupezeka kwa Liquid Sodium Cyanide
pamene sodium cyanide ndi olimba kutentha firiji, akhoza kupezeka mu mawonekedwe amadzimadzi pansi pa zinthu zinazake. Mwachitsanzo, m'mafakitale, pamene sodium cyanide imasungunuka muzosungunulira zoyenera kupanga njira yamadzimadzi, imatha kukhala yamadzimadzi - ngati boma lazinthu zosiyanasiyana zama mankhwala. Komanso, ngati kutentha kwakwera pamwamba pa malo ake osungunuka, kumasandulika kukhala madzi. Koma izi siziri mikhalidwe ya kutentha kwa chipinda.
Pomaliza, pansi pa kutentha kwa chipinda, sodium cyanide ndi yolimba. Chifukwa cha kawopsedwe kake kwambiri, kugwiritsa ntchito kulikonse kwa sodium cyanide, kaya ndi mawonekedwe olimba kapena amadzimadzi, kuyenera kuchitidwa mosamala kwambiri, kutsatira malamulo okhwima otetezedwa kuti apewe kuvulaza thanzi la anthu komanso chilengedwe.
