Chloride Mercuric (sublimate xoqe): Diyaarinta, Guryaha iyo Codsiyada

Waa wax qarsoodi ah xeryahooda mercury aadka sun ah iyo sunta. In Maraykanka, waxay waxaa ka mamnuuc ah in loo isticmaalo in inta badan waxyaabaha quruxda, iyo Kanada ayaa lagu daray liiska ka mid ah walxaha ugu halista ah. Si kastaba ha ahaatee, ay si ballaaran loo adeegsado warshadaha kiimikada ah ee soo saaridda ee formaldehyde, fungicides, bacyaal, iyo sidoo kale in daawada iyo farsamada. Mid ka mid ah wakiilo ka class this of walxaha waa chloride mercury (II), kaas oo si fiican u yaqaan ay magaca labaad - sublimate. Bal aynu eegno xiriir this si faahfaahsan.

Formula iyo hantida

Mercury chloride 2-valent qoondeeyey HgCl _2. Xarunta Tani waa budo crystalline cad. Heerkulka 277˚ C a wuxuu bilaabaa inuu dhalaalin, iyo marka 304˚S - karaya. In xaaladaha caadiga ah (25 ° C) uu leeyahay cufnaanta ah 5,43 g / cm ^3. sublimes chloride Mercuric si fudud u kala duwan Degenaansho appreciable. milmi The of chloride mercuric biyo inta badan ku xiran tahay heerkulka. Sidaas, at 20 ° C, tiradaasi waa kaliya 6.6%, laakiin waxaa lagama maarmaan ah inay biyo ku kari a (100 ° C) keena, oo waxay gaadhaysaa 58.3%. Intaa waxaa dheer, mercury waa chloride awood u diri ee ether, acids, pyridine; xal NaCl in habkan waxaa la socda dhismaha xeryahooda adag. HgCl ₂ sida elektrolytka waa quruxsan daciif ah. In la badallo, gaar ahaan marka ay xiriir la xeryahooda organic, maalkiisu waa diyaar hoos u chloride cuprous Hg ₂ cl ₂ (calomel) iyo Meerkuridu macdan ah.

soo dhaweynta

In tiro badan oo ah chloride mercury (II) waxaa hadda la soo saaray oo kaliya taasi oo ka Avv toos ah oo ka mid ah mercury iyo chlorine. Habka labaad helo ka kooban yahay ee kala diridda mercuric HgO in xoog aashito (HCL). In dhaqanka, waxaa dhif ah loo isticmaalo, inta badan - in koorsada of fulinta baaritaan sheybaar. Xaaladda hore, mercury la kululeeyo in jawi chlorine in heerkulka aad u sarreeya (qiyaastii 340˚S) ka dibna u guban iyo formation of olol buluug-cad gubi. The uumi ka keentay waa la aruurshey inta lagu guda jiro qaboojinta iyo, iyada oo ku xiran technology ee helitaanka, foomka budada ah ganaax ama qaybo adag.

codsiga

Waa in la ogaadaa in chloride mercuric ahaa walax ugu horeysay ku saleysan Hg, oo waxay bilaabeen inay in la isticmaalo sida aalkolada iyo jeermiska. Marka tan la eego, chloride mercuric waa aad u waxtar fiican, laakiin waqti isku mid ah waa mid aad u sun ah. Waa in la nuugo maqaarka iyo xabka xuubka iyo uruursado ee jirka aadanaha awoodaan. Horaantii, marka dadku ma aan ogayn oo ku saabsan khatarta by chloride mercury, waxaa loo isticmaalaa in lagu daaweeyo cudurrada maqaarka. Haddaba, in dawada loo isticmaalo dheeraad ah oo dhar-dilista, dharka, alaabta caafimaadka, iwm Tan iyo walax tani waa mid aad u sun ah, xal ay inta badan si gaar ah la caseeyey in qofkii qaldamay waa lama qaso daawooyin kale.

In warshadaha, chloride mercury waxaa loo isticmaalaa in electroforming, ilaalinta alwaax, inta lagu guda jiro metallization kaamerada iyo bronzing. chloride Mercuric loo isticmaalo soo saaridda ee batariyo, midabeeyo ee godadka quuska maraakiibta. Waxa loo isticmaalaa in warshadaynta ee maqaar, lithography, sawir, sida cayayaanka ah, iwm
