Menene Abubuwan Jiki na Sodium Cyanide?

sodium Cyanide (NaCN) wani sinadari ne wanda ya ja hankali sosai saboda gubarsa da aikace-aikacen masana'antu. Fahimtar ta jiki Properties yana da mahimmanci don kulawa, ajiya, da la'akarin aminci. Anan akwai manyan kaddarorin jiki na Sodium cyanide:

1. Appearance: sodium cyanide yawanci yana bayyana azaman fari, granules crystalline, foda, ko kullutu. A cikin tsantsar sigar sa, yana da tsaftataccen siffa mara launi lokacin da yake cikin bayani ko a matsayin kristal bayyananne. Koyaya, samfuran kasuwanci na iya bayyana a wasu lokuta a kashe kaɗan - fari saboda ƙazanta.

2. wari: Yana da suma, halayyar almond - kamar wari. Amma yana da mahimmanci a lura cewa ba kowa bane ke iya gano wannan warin. An ƙaddara ikon jin warin mahaɗan cyanide ta hanyar kwayoyin halitta, tare da wani yanki mai mahimmanci na yawan jama'a ba za su iya gane warin ba. Bugu da ƙari, a cikin yanayin bushewa. sodium Cyanide sau da yawa ba shi da wari. Kamshin yana ƙara fitowa ne idan aka fallasa shi ga iska ko ruwa mai ɗanɗano, yayin da yakan yi hydrolyzes ya saki hydrogen cyanide (HCN), wanda ke da kamshin almond da aka sani.

3. Narkewa Da Tafasa: Sodium cyanide yana da matsakaicin matsakaicin matsakaiciyar narkewa kamar 563.7 °C (1046.7 °F). Wannan yana nuna ƙarfi na ionic bond a cikin fili. Wurin tafasarsa yana kusa da 1496 ° C (2725 ° F). Wadannan manyan narkewa da wuraren tafasa sune nau'in mahadi na ionic, inda karfi mai karfi na electrostatic na jan hankali ya kasance tsakanin sodium cations (Na⁺) da cyanide anions (CN⁻).

4. yawa: Yawan yawa sodium cyanide kusan 1.595 g/cm³. Wannan ƙima mai yawa yana taimakawa wajen ƙayyade adadin abu a cikin ƙarar da aka ba da shi, wanda ke da mahimmanci ga aikace-aikacen masana'antu da hanyoyin sarrafawa.

5. solubility: Sodium cyanide yana narkewa sosai a cikin ruwa. A 20 ° C, kusan gram 48 na sodium cyanide zai iya narke a cikin milliliters 100 na ruwa. Yayin da zafin jiki ya ƙaru, ƙarfinsa kuma yana ƙaruwa. Misali, a 34.7 ° C, kimanin gram 82 na iya narke a cikin milliliters 100 na ruwa. Hakanan yana narkewa sosai a cikin ethanol kuma yana narkewa a cikin sauran kaushi na polar kamar ammonia. A cikin ruwa, yana rarraba zuwa ions sodium (Na⁺) da ion cyanide (CN⁻), waɗanda ke da alhakin yawancin abubuwan sinadarai da toxicological.

6. Hygroscopicity: Sodium cyanide ne hygroscopic, ma'ana yana da hali na sha danshi daga iska. Lokacin da ya sha ruwa, zai iya haifar da hydrates. A wasu lokuta, wannan na iya haifar da caking ko clumping na ƙaƙƙarfan abu idan an adana shi a cikin yanayi mai ɗanɗano. Ita ma wannan kadarar tana da tasiri wajen ajiyarta, domin tana buqatar a ajiye ta a busasshiyar wuri don kiyaye mutuncinta da kuma hana abubuwan da ba a so.

7. Shafin Farko: Ma'anar refractive na sodium cyanide shine kusan 1.452. Fihirisar refractive shine ma'auni na yawan haske da ake lankwasa lokacin da ya wuce ta wani abu. Ana iya amfani da wannan kadarorin a cikin dabarun nazari don ganowa da kuma siffanta sodium cyanide a wasu yanayi, musamman a hade tare da sauran kaddarorin jiki da sinadarai.

A taƙaice, sifofin jiki na sodium cyanide, kamar bayyanarsa, ƙamshi, narkewa da wuraren tafasawa, yawa, solubility, hygroscopicity, da fihirisar raɗaɗi, suna taka muhimmiyar rawa wajen amfani da masana'antu da hanyoyin kula da aminci. Ganin matsananciyar gubarsa, sanin waɗannan kaddarorin yana da mahimmanci ga waɗanda ke aiki tare da ko kewayen wannan fili.
