Ihe onwunwe

Phe chemical usoro nke ọlaọcha oxide bụ Ag2O, na a molekụla arọ nke 231.74.Agba aja aja ma ọ bụ isi awọ ojii siri ike, nke nwere njupụta nke 7.143g/cm, na-emebi ngwa ngwa wee mepụta ọlaọcha na oxygen na 300 ℃.Na-agbaze ntakịrị na mmiri, na-agbaze nke ukwuu na nitric acid, amonia, sodium thiosulfate, na ngwọta cyanide potassium.Mgbe a na-eji ngwọta amonia eme ihe, a ghaghị ịgwọ ya n'oge kwesịrị ekwesị.Mkpughe ogologo oge nwere ike ịkpali kristal ojii na-agbawa agbawa - nitride ọlaọcha ma ọ bụ sulfite ọlaọcha.Ejiri ya dị ka oxidant na iko agba.Kwadoro site na imeghachi ngwọta nitrate ọlaọcha na ngwọta sodium hydroxide.

Ihe onwunwe kemịkalụ

Tinye ihe ngwọta caustic na ngwọta nitrate ọlaọcha iji nweta ya.Nke mbụ, a na-enweta ihe ngwọta nke silver hydroxide na nitrate, na ọlaọcha hydroxide na-emebi n'ime ọlaọcha oxide na mmiri na ụlọ okpomọkụ.Silver oxide na-amalite ire ere mgbe ọ na-ekpo ọkụ ruo 250 ℃, na-ahapụ oxygen, na-agbaze ngwa ngwa karịa 300 ℃.Na-agbaze ntakịrị na mmiri, mana ọ na-agbaze nke ukwuu na ngwọta dị ka nitric acid, amonia, potassium cyanide, na sodium thiosulfate.Mgbe ekpughere ogologo oge na ngwọta amonia ya, kristal ojii na-agbawa agbawa nwere ike ịmalite mgbe ụfọdụ - ikekwe ọlaọcha nitride ma ọ bụ ọlaọcha iminide.Na njikọ organic, a na-ejikarị otu hydroxyl dochie halogens ma ọ bụ dị ka oxidants.Enwere ike iji ya mee ihe dị ka agba na ụlọ ọrụ iko.

 

Usoro nkwadebe

Enwere ike nweta oxide ọlaọcha site na imeghachi alkali metal hydroxide na nitrate ọlaọcha.[1] Mmeghachi omume mbụ na-ebute silver hydroxide nke na-adịghị akwụsi ike, nke na-emebi ozugbo iji nweta mmiri na ọlaọcha oxide.Mgbe ịsachara mmiri ozuzo, a ghaghị ịmịchaa ya na ihe na-erughị 85 Celsius C, ma ọ na-esiri ike iwepụ obere mmiri site na ọlaọcha oxide na njedebe n'ihi na ka okpomọkụ na-abawanye, ọlaọcha oxide ga-emebi.2 Ag+ + 2 OH- → 2 AgOH → Ag2O + H2O.

 

Isi ojiji

A na-ejikarị eme ihe dị ka ihe na-akpali akpali maka njikọ kemịkal.A na-ejikwa ya dị ka ihe nchekwa, ngwa eletrọnịkị, agba agba iko, na ihe egweri.Ejiri ya mee ihe maka ahụike yana dị ka ihe na-eme ka iko na-egbuke egbuke, agba agba, na mmiri na-asachapụ;Ejiri ya dị ka ihe na-egbuke egbuke na agba maka iko.

 

Oke ngwa

Silver oxide bụ ihe electrode maka batrị ọlaọcha oxide.Ọ bụkwa ihe na-adịghị ike oxidant na isi adịghị ike na njikọ nke organic, nke nwere ike imeghachi ya na salts imidazole 1,3-disubstituted na benzimidazole salts iji mepụta azenes.Ọ nwere ike dochie ligands na-ejighị n'aka dị ka cyclooctadiene ma ọ bụ acetonitrile dị ka carbene transfer reagents iji synthesize mgbanwe metal carbene ogige.Na mgbakwunye, ọlaọcha oxide nwere ike ịgbanwe organic bromides na chlorides n'ime mmanya na obere okpomọkụ na n'ihu mmiri vepo.A na-eji ya na iodomethane dị ka methylation reagent maka nyocha methylation shuga na mmeghachi omume mkpochapụ Hoffman, yana maka oxidation nke aldehydes na carboxylic acid.
