Isingeniso:
Uke uzibuze ukuthi kunganiisiliva oxideimelwe ifomula yamakhemikhali ethi Ag2O?Yakhiwa kanjani le nhlanganisela?Ihluke kanjani kwamanye ama-oxide ensimbi?Kule bhulogi, sizohlola i-chemistry ethakazelisayoisiliva oxidefuthi yembule izizathu zesakhiwo sayo esiyingqayizivele samangqamuzana.
Funda mayelanaisiliva oxide:
I-Silver oxide (Ag2O)iyinhlanganisela ye-inorganic eyakhiwe ngama-athomu esiliva (Ag) kanye ne-oxygen (O).Ngenxa yemvelo yayo eyisisekelo, ihlukaniswa njenge-oxide eyisisekelo.Kodwa kungani ibizwa nge-Ag2O?Ake simbe ukwakheka kwayo ukuze sithole.
Ukwakheka kweisiliva oxide:
I-Silver oxide yakheka ngokuyinhloko ngokusabela phakathi kwesiliva nomoya-mpilo.Lapho insimbi yesiliva ihlangana nomoya, inqubo ye-oxidation ehamba kancane iyenzeka, yakheisiliva oxide.
2Ag + O2 → 2Ag2O
Lokhu kusabela kwenzeka kalula lapho kushisisiwe, okuvumela ama-athomu esiliva ukuthi asabele ngokuphumelelayo nama-molecule omoya-mpilo, agcine akheke.isiliva oxide.
Isakhiwo samangqamuzana esiyingqayizivele:
Ifomula yamangqamuzanaAg2Oibonisa ukuthi i-oxide esiliva iqukethe ama-athomu amabili esiliva ahlanganiswe ne-athomu eyodwa yomoya-mpilo.Ukuba khona kwama-athomu amabili esiliva kunikeza i-silver oxide i-stoichiometry eyingqayizivele eyenza ihluke kwamanye ama-oxide ensimbi.
I-Silver oxideyamukela isakhiwo sekristalu esikhethekile esibizwa nge-inverse fluorite, okuphambene nesakhiwo esivamile se-fluorite.Esakhiweni se-antifluorite, ama-athomu omoya-mpilo akha uhlu olugcwele eduze, kuyilapho ama-ion esiliva ethatha izikhundla ze-tetrahedral interstitial ngaphakathi kwe-oxygen crystal lattice.
Izici Nezicelo:
I-Silver oxideinezindawo eziningana ezithakazelisayo ezenza ibe yigugu emikhakheni ehlukene.Nazi ezinye izici eziphawulekayo:
1. I-alkaline:I-Silver oxideibhekwa njengenhlanganisela ye-alkaline futhi ibonisa izakhiwo ze-alkaline lapho incibilika emanzini, njengamanye ama-oxide ensimbi.
2. Ukuzwela kwesithombe:I-Silver oxidei-photosensitive, okusho ukuthi iba nokusabela kwamakhemikhali lapho ichayeke ekukhanyeni.Le ndawo iholele ekusetshenzisweni kwayo kumafilimu ezithombe nanjenge-photosensitizer ezinhlobonhlobo zezinhlelo zokusebenza.
3. Izici zokulwa namagciwane: Ngenxa yezakhiwo zayo zokulwa namagciwane,isiliva oxideisetshenziswa kwezokwelapha, ikakhulukazi njenge-antibacterial enamathela ezinsimbini zokuhlinza nezingubo zamanxeba.
4. Umsebenzi we-Catalytic:I-Silver oxideisebenza njenge-catalyst ekuphenduleni kwamakhemikhali athile e-organic.Ingasetshenziswa njengokwesekwa kwe-catalyst ezinqubweni eziningi zezimboni, njengokusabela kwe-oxidation.
Ekuphetheni:
I-Silver oxideiyaqhubeka nokuthakazelisa osokhemisi nabacwaningi emhlabeni wonke ngesakhiwo sayo esiyingqayizivele samangqamuzana nezinto ezithakazelisayo.IAg2OIfomula yamangqamuzana igqamisa inhlanganisela ethokozisayo yama-athomu esiliva ne-oxygen, okwenza inhlanganisela enokusetshenziswa okuhlukahlukene, kusukela ekuthwebuleni kuya kwezokwelapha kanye ne-catalysis.
Ukuqonda i-chemistry ngemuvaisiliva oxideakwanelisi nje kuphela ilukuluku lethu kodwa futhi liyisibonelo sezakhiwo eziyinkimbinkimbi zenhlanganisela.Ngakho ngesikhathi esilandelayo lapho uhlangana khona ne-Ag2Oifomula yamangqamuzana, khumbula izici eziphawulekayo nokusebenza okuhlobene ne-silver oxide, konke okubangelwa ukuhlelwa ngokucophelela kwama-athomu.
