Thepa ea nama

Phe chemical formula of silver oxide ke Ag2O, e nang le boima ba molek'hule ea 231.74. Bosootho bo bosootho kapa bo boputsoa bo bosootho, bo boholo ba 7.143g/cm, bo bola ka potlako ho etsa silevera le oksijene ho 300 ℃. E qhibiliha hanyane ka metsing, e qhibiliha haholo ho nitric acid, ammonia, sodium thiosulfate, le potassium cyanide solutions. Ha tharollo ea ammonia e sebelisoa, e lokela ho phekoloa ka nako e loketseng. Ho pepeseha ha nako e telele ho ka baka likristale tse ntšo tse phatlohang haholo - silver nitride kapa silver sulfite. E sebelisoa e le 'mala oa oxidant le khalase. E lokiselitsoe ka ho arabela tharollo ea silevera ea nitrate ka tharollo ea sodium hydroxide.

Brown cubic crystalline kapa phofo e ntšo e sootho. Bond bolelele (Ag O) 205pm. Ho bola ka likhato tse 250, ho lokolla oksijene. Boima ba 7.220g/cm3 (25 degrees). Leseli lea bola butle-butle. Etsa ka asiti ea sulfuric ho hlahisa sulfate ea silevera. E qhibiliha hanyane ka metsing. E qhibiliha ka metsing a ammonia, sodium hydroxide solution, dilute nitric acid, le sodium thiosulfate solution. Ha e qhibilihe ka har'a ethanol. E lokiselitsoe ka ho arabela tharollo ea silevera ea nitrate ka tharollo ea sodium hydroxide. Ag2O e metsi e sebelisoa e le sesosa ha ho nkela li-halogen sebaka ka lihlopha tsa hydroxyl ka har'a organic synthesis. E boetse e sebelisoa e le thepa ea ho boloka le ea lisebelisoa tsa elektroniki.

 

Thepa ea lik'hemik'hale

Eketsa tharollo ea caustic ho tharollo ea silevera ea nitrate ho e fumana. Taba ea pele, tharollo ea silevera ea hydroxide le nitrate e fumanoa, 'me hydroxide ea silevera e senyeha ka oxide ea silevera le metsi ka mocheso oa kamore. Silver oxide e qala ho bola ha e futhumatsoa ho 250 ℃, e ntša oksijene, 'me e bola ka potlako ka holimo ho 300 ℃. E qhibiliha hanyenyane metsing, empa e qhibiliha haholo ka litharollo tse kang nitric acid, ammonia, potassium cyanide, le sodium thiosulfate. Kamora ho pepesehela tharollo ea ammonia nako e telele, ka linako tse ling likristale tse ntšo tse phatlohileng li ka putlama - mohlomong silver nitride kapa silver nitride. Ho organic synthesis, lihlopha tsa hydroxyl li atisa ho sebelisoa ho nkela li-halogen kapa e le li-oxidants. E ka boela ea sebelisoa e le colorant indastering ea likhalase.

 

Mokhoa oa ho lokisetsa

Silver oxide e ka fumanoa ka ho arabela alkali metal hydroxide le silver nitrate. [1] Karabelo ea pele e hlahisa silevera e sa tsitsang ea hydroxide, eo hang-hang e senyehang ho fumana metsi le silevera oxide. Ka mor'a ho hlatsoa precipitate, e tlameha ho omisoa ka tlase ho 85 ° C, empa ho thata haholo ho tlosa metsi a seng makae ho tloha oxide ea silevera qetellong hobane ha mocheso o ntse o eketseha, oxide ea silevera e tla senyeha. 2 Ag+ + 2 OH− → 2 AgOH → Ag2O + H2O.

 

Tšebeliso ea motheo

Haholo-holo e sebelisoa e le sesosa sa motsoako oa lik'hemik'hale. E boetse e sebelisoa e le ntho e sireletsang, lisebelisoa tsa lisebelisoa tsa elektroniki, 'mala oa khalase le ntho e silang. E sebedisetsoa merero ea bongaka le joalo ka sesebelisuoa sa ho bentša likhalase, setlolo sa mebala le se hloekisang metsi; E sebelisoa e le sesebelisoa sa ho bentša le ho kenya mebala bakeng sa khalase.

 

Sebaka sa kopo

Silver oxide ke thepa ea elektrode bakeng sa libeteri tsa silevera tsa oxide. Hape ke setsi se fokolang sa oxidant le se fokolang ho organic synthesis, e ka sebetsanang le matsoai a imidazole a 1,3-disubstituted le matsoai a benzimidazole ho hlahisa azenes. E ka nka sebaka sa li-ligands tse sa tsitsang tse kang cyclooctadiene kapa acetonitrile e le li-reagents tsa ho fetisa carbene ho kopanya li-transition metal carbene complexes. Ho phaella moo, silevera ea oxide e ka fetola li-bromide le li-chloride tsa organic hore e be lino tse tahang ka mocheso o tlase le boteng ba mouoane oa metsi. E sebelisoa mmoho le iodomethane e le reagent ea methylation bakeng sa tlhahlobo ea tsoekere ea methylation le karabelo ea ho felisa Hoffman, hammoho le bakeng sa oxidation ea aldehydes ho carboxylic acid.
