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 ime ihe ngwọta nitrate ọlaọcha na ngwọta sodium hydroxide.

kristal cubic Brown ma ọ bụ ntụ ntụ ojii. Ogologo nkwekọ (Ag O) 205pm. Nbibi na ogo 250, na-ahapụ oxygen. Njupụta 7.220g/cm3 (25 degrees). Ìhè ahụ na-eji nwayọọ nwayọọ rebie. Jiri sulfuric acid mee ihe iji mepụta sulfate ọlaọcha. Na-agbaze ntakịrị na mmiri. Na-agbaze na mmiri amonia, ngwọta sodium hydroxide, dilute nitric acid, na sodium thiosulfate ngwọta. Na-adịghị ike na ethanol. Kwadoro site na imeghachi ngwọta nitrate ọlaọcha na ngwọta sodium hydroxide. A na-eji Wet Ag2O mee ihe dị ka ihe na-akpali akpali mgbe ọ na-eji otu hydroxyl dochie halogens na njikọ organic. A na-ejikwa ya dị ka ihe nchekwa na ngwá electronic.

 

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 silver 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 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 nnu 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. Tụkwasị na nke ahụ, ọlaọcha oxide nwere ike ịtụgharị organic bromides na chlorides n'ime mmanya na-egbu egbu na obere okpomọkụ na n'ihu ikuku mmiri. 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.
