Hantida jirka

Qaaciddada kiimikada Phe ee oksaydhka qalinka ah waa Ag2O, oo leh miisaan kelli ah 231.74.Madaw ama cawl madow oo adag, cufnaanta 7.143g/cm, si degdeg ah u qudhuntaa si ay u samayso qalin iyo ogsijiin at 300 ℃.In yar oo biyo ku milmay, aad ugu milmay nitric acid, ammonia, sodium thiosulfate, iyo xalalka cyanide potassium.Marka xalka ammonia la isticmaalo, waa in lagu daaweeyaa waqti ku habboon.Soo-gaadhista muddada dheer waxay soo dajin kartaa kiristaalo madow oo aad u qarxa - nitride silver ama sulfite silver.Loo isticmaalo sidii oksaydhiyaha iyo midabka dhalada.Waxaa loo diyaariyey iyada oo ka falcelinaysa xal nitrate qalin ah oo leh xal sodium hydroxide.

crystalline cubic Brown ama budada madow ee bunni.Dhererka dammaanadda (Ag O) 205 galabnimo.Burburka 250 darajo, soo daaya ogsijiinta.Cufnaanta 7.220g/cm3 (25 darajo).Iftiinku si tartiib tartiib ah ayuu u burburaa.Ku fal celi sulfuric acid si aad u soo saarto sulfate qalin ah.Waxoogaa ku milmay biyaha.Ku milmay biyaha ammonia, xal sodium hydroxide, milmi nitric acid, iyo sodium thiosulfate.Aan ku milmin ethanol.Waxaa loo diyaariyey iyadoo lagu falcelinayo xal nitrate silver ah oo leh xal sodium hydroxide.Qoyan Ag2O waxaa loo isticmaalaa kicin ahaan marka halogens lagu beddelo kooxaha hydroxyl ee isku-dhafka dabiiciga ah.Waxa kale oo loo isticmaalaa sida agabka ilaalinta iyo qalabka elegtarooniga ah.

 

Hantida kiimikada

Ku dar xal caustic ah xalka nitrate-ka qalinka ah si aad u hesho.Marka hore, xalalka hydroxide silver iyo nitrate ayaa la helayaa, iyo hydroxide silver wuxuu u jajabiyaa oksaydhka qalinka iyo biyaha heerkulka qolka.Oksijiinta Silver waxay bilaabataa inay qudhunto marka la kululeeyo ilaa 250 ℃, taasoo sii daynaysa ogsijiinta, oo si degdeg ah u qudhuntaa in ka badan 300 ℃.Waxoogaa ku milmay biyaha, laakiin aad ugu milmay xalalka sida nitric acid, ammonia, potassium cyanide, iyo sodium thiosulfate.Ka dib soo-gaadhista dheer ee xalkeeda ammonia, kiristaalo madow oo xooggan ayaa laga yaabaa inay mararka qaarkood soo da'aan - laga yaabee nitride silver ama silver iminide.Isku-dhafka dabiiciga ah, kooxaha hydroxyl waxaa badanaa loo isticmaalaa in lagu beddelo halogens ama sida oksidants.Waxa kale oo loo isticmaali karaa sida midabaynta warshadaha galaaska.

 

Habka diyaarinta

Osaydhka qalinka ah waxa lagu heli karaa ka falcelinta birta alkali hydroxide oo leh nitrate qalin ah.[1] Dareen-celinta marka hore waxay dhalisaa hydroxide silver aadka u deggan, kaas oo isla markiiba baaba'a si uu u helo biyo iyo oksaydh qalin ah.Ka dib marka la dhaqo roobka, waa in lagu qallajiyaa wax ka yar 85 ° C, laakiin aad bay u adag tahay in laga saaro qadar yar oo biyo ah oksaydhka qalinka dhamaadka sababtoo ah marka heerkulku kordho, oksaydhka qalinku wuu dumin doonaa.2 Ag+ + 2 OH− → 2 AgOH → Ag2O + H2O.

 

Isticmaalka aasaasiga ah

Inta badan loo isticmaalo sidii kicinta isku-dhafka kiimikada.Waxa kale oo loo istcimaalaa sidii wax-ilaaliye, qalab elegtaroonig ah, midab dhalada ah, iyo wakiilka wax shiida.Loo isticmaalo ujeeddooyin caafimaad iyo sida walax dhalada dhalaalaysa, midabaynta, iyo nadiifiyaha biyaha;Loo isticmaalo sidii midabaynta iyo midabaynta dhalada.

 

Baaxadda codsiga

Silver oxide waa walxaha korantada ee baytariyada oksaydhka qalinka ah.Sidoo kale waa oksaydhiyaha daciifka ah iyo saldhigga daciifka ah ee isku-dhafka dabiiciga ah, kaas oo ka falcelin kara 1,3-cusbada imidazole iyo cusbada benzimidazole si loo dhaliyo azenes.Waxay bedeli kartaa isku-xidhka aan xasilloonayn sida cyclooctadiene ama acetonitrile sida reagents wareejinta carbene si ay u abuurto dhismooyinka carbene ee birta ee kala guurka ah.Intaa waxaa dheer, oksaydhka qalinku wuxuu u beddeli karaa bromides organic iyo chlorides khamriga heerkulka hooseeya iyo joogitaanka uumiga biyaha.Waxaa loo isticmaalaa iyadoo lala kaashanayo iodomethane sida reagent methylation ee falanqaynta methylation sonkorta iyo falcelinta Hoffman baabi'inta, iyo sidoo kale oksaydhka aldehyde ilaa asiidhyada karboksilic.
