Xabagta copper

Cuprum (CU) waxaa loola jeedaa tirada Biraha firfircoonayn. Waxaa lagu gartaa formation of kiimiko ah dalalka qayilo ee +1 oo +2. Tusaale ahaan, labada oxides, waa xarunta ah laba cunsur ee CU iyo oxygen O: qayilo gobolka +1 - Cu2O xabagta cuprous iyo gobolka qayilo +2 ah - xabagta copper CuO. In kasta oo xaqiiqda ah in ay ka kooban oo ka mid ah xubno ka kiimikada isku mid ah, laakiin mid kasta oo iyaga ka mid ah waxay leedahay astaamo u gaar ah oo ay u gaar ah. In biraha qabow jawaabay aad u imaanshada la oxygen hawada, daboolay filim, taas oo ah xabagta naxaas ah, taasoo ka hortagaysa rakiban qayilo cuprum. Marka kululeeyo, walax fudud tiro isku xigxiga oo 29 in miiska wareegsan buuxda oxidized. Xaaladdan oo kale ayaa sidoo kale la aasaasay of xabagta copper (II): 2Cu + O2 → 2CuO.

xabagta nitrus waa brownish-cas adag oo leh miisaan ah kelli ah 143,1 g / jirjirroolaha. Xarunta waxay leedahay heerkulka barafku ee 1235 ° C, dhibic karaya ee 1800 ° C. a a Waxa aanu baabbi'isaa biyaha, laakiin kala diray in acids. xabagta copper koray (I) ee xal ammonia (urursan), la xirrira ah midab adag [CU (NH3) 2] +, taas oo si fudud oxidized hawada si ammonia midab buluug-guduudan oo adag [CU (NH3) 4 (H2O) 2] 2+ kala diridda in aashito si ay u sameeyaan CuCl2. In taariikhda physics Semiconductor Cu2O waa mid ka mid ah waxyaabaha ugu bartay.

xabagta Copper (I), sidoo kale loo yaqaan nitrus wuxuu leeyahay sifooyin aasaasi ah. Waxaa la diyaarin karaa by qayilo ee biraha: 4Cu + O2 → 2 Cu2O. Nijaasta ahaa sida biyaha iyo acid in ay saameeyaan heerka of habka this, iyo qayilo dheeraad ah si xabagta ferrous. xabagta Cuprous waxaa la kala diri karaa sulfuric acid, oon la xirrira biraha daahir ah iyo cusbo ah, waayo, H2SO4 + Cu2O → CU + CuSO4 + H2O. nidaamka la mid ah waa is dhexgalka ah ee xabagta la degree ah lagu qayilo ka mid ah biraha la acids kale oxygen-ka kooban. In falcelinta ee nitrus acid foomka cusbo biraha monovalent halogenated: 2HCl + Cu2O → 2CuCl + H2O.

Found xabagta copper (I) ee dabiiciga ah sida ore cas (magacan jir ah, oo ay la socdaan sida guduud CU), macdanta loo yaqaan "Cuprite". On ay formation qaadataa waqti dheer. Waxaa la soo saaray karaa kiimikaysan ama heerkulka sare cadaadis oxygen sare. Nitrus sida caadiga ah loo isticmaalo sida ku masax ah, sida Midabka ah, sida wakiilka antifouling quuska in rinjiga ama badda, oo sidoo kale loo isticmaalaa sidii qaar kaaliya.

Si kastaba ha ahaatee, saamaynta ay walax la Cu2O formula kiimikada on shaqeeyo waxaa laga yaabaa in waxyeello. Marka lagu neefsado, waxa sababa neefta oo ku qabata, qufac, iyo ulceration iyo daloolin of mareenka-mareenka. Haddii liqay, diiqayo in mareenka caloosha iyo mindhicirka, Ulasocto matag, xanuun iyo shuban.

xabagta Higher copper muuqaalka waa budo ka brown madow. Waxaa dabiici ah waxay dhacdaa sida macdanta ah, "xukunka" ay foomka saafi ah. heerkulka barafku Its waa 1326 ° C, karkaraya dhibic 2,000 ° C. Waa beelaya biyo, khamriga, hydroxide ammonium, xal carbonate ammonium. L. in xal aqueous of chloride ammonium iyo cyanide potassium. Tani adag madow waxaa laga heli karaa by kulaylinta in CU hawada. Si kastaba ha ahaatee, haddii ay taasi sidoo kale sameeyay CU xabagta. Diyaarinta xabagta copper CuO optionally la xeryahooda kululaynta:

• copper (II) amooniyam 2Cu (NO3) 2 4 → NO2 + O2 + 2CuO;

• copper (II) hydroxide CU (OH) 2 → H2O + CuO;

• copper (II) carbonate CuCO3 → CO2 + CuO.

Cuprum (II) xabagta waa aasaasiga ah, sidaa daraadeed waxa uu u kala diray in acids macdanta (Hydrochloric, sulfuric iyo nitric) in la siiyo dhiganta divalent CU cusbada:

• 2HCl + CuO → CuCl2 + H2O;

• H2SO4 + CuO → CuSO4 + H2O;

• 2HNO3 + CuO → CU (NO3) 2 + H2O.

Sameynayso xabagta copper (II) la alkali ah ku urursan si ay u sameeyaan cusbo ah: 2 Koh + CuO + H2O → K2 [CU (OH) 4].

xabagta ayaa sidoo kale laga yaabaa in la yareeyo inay macdan CU by reaction la hydrogen ama carbon monoxide :

• H2 + CuO → CU + H2O;

• CO + CuO → CU + CO2.

Isticmaalka xabagta copper (II) ee dhoobada (sida Midabka a) waayo, glaze ah (buluug, cagaar iyo casaan, iyo mararka qaarkood casaan, boor ama madow). Waxaa sidoo kale loo isticmaalaa sida daro cuntada ee neef xayawaan ah si loo yareeyo yarida cuprum ee jirka. Macluumaadkaan waxaa sugi lahaayeen, taas oo loo baahan yahay in qalabka indhaha dhalaalin. Waxa loo isticmaalaa wax soo saarka ee batariyo qalalan diyaarinta cusbada kale CU. Xarunta ayaa waxaa sidoo kale loo isticmaalaa in CuO Alloys copper alxanka.

Gaadhista xarunta kiimikada CuO sidoo kale noqon karaa mid halis u ah jirka aadanaha. Markay neefta, taasoo keenta sambabada cuncun. xabagta Copper (II) waxay keeni kartaa uumi macdan ah qandho (MFF). xabagta CU dhirfinaya isbeddel ku midabka maqaarka, waxaa laga yaabaa in ay leeyihiin dhibaato la aragga indhaha. Marka daama sida nitrus keenaysaa in lagu sumoobo, kaas oo la Ulasocto calaamadaha matag iyo xanuun.
