Folasaga:
Mafaufau pea pe aiseaoxide silivao lo'o fa'atusalia e le fua fa'atatau kemikolo Ag2O?E fa'afefea ona fa'atupuina lea fa'apotopotoga?E faapefea ona ese mai isi uamea oxides?I lenei blog, o le a matou suʻesuʻeina le kemisi mataʻina ooxide silivama fa'ailoa mai mafua'aga i tua atu o lona fausaga mole mole tulaga ese.
Aoao e uiga ioxide siliva:
Silver oxide (Ag2O)o se fa'aputu fa'a-organic e fa'atūina i le ario (Ag) ma le okesene (O).Ona o lona natura faavae, ua faavasegaina o se oxide faavae.Ae aiseā ua taʻua ai Ag2O?Se'i tatou su'esu'e i lona faiga ina ia iloa ai.
O le faavaeina ooxide siliva:
O le oxide siliva e masani lava ona fausia e ala i le tali i le va o le siliva ma le okesene.Pe a oʻo mai le uamea siliva i le ea, e tupu se faʻagasologa faʻamaʻi faʻamaʻi, faʻavaeoxide siliva.
2Ag + O2 → 2Ag2O
O lenei tali e sili atu ona faigofie pe a faʻamafanafanaina, faʻataga ai atoms siliva e tali lelei atu i mole okesene, mulimuli ane fausia.oxide siliva.
Tulaga mole mole fausaga:
Le fua moleAg2Oo lo'o ta'u mai ai o le oxide siliva o lo'o i ai ni atoma siliva se lua o lo'o pipii i se atoma okesene se tasi.O le i ai o ni mea siliva se lua e maua ai le oxide siliva se stoichiometry tulaga ese e tu'u ese ai mai isi oxide u'amea.
Silver oxidefaʻaaogaina se fausaga tioata faʻapitoa e taʻua o le fluorite inverse, o le faʻafeagai lea o le fausaga masani o le fluorite.I totonu o le fausaga o le antifluorite, o le okesene okesene e fausia ai se laina vavalalata, ae o ion siliva o loʻo nofoia tulaga faʻava-o-tetrahedral i totonu o le lattice tioata okesene.
Vaega ma Fa'aoga:
Silver oxideo lo'o i ai le tele o mea mananaia e fa'atauaina i vaega eseese.O nisi nei o mea mata'ina:
1. Alkaline:Silver oxidee fa'atatauina ose fa'afefiloi alkaline ma fa'aalia uiga alkaline pe a fa'amavae i le vai, pei o isi u'amea u'amea.
2. Photosensitivity:Silver oxidee photosensitive, o lona uiga e oʻo i se gaioiga faʻamaʻi pe a faʻaalia i le malamalama.O lenei meatotino ua mafua ai lona faʻaaogaina i ata tifaga ma avea o se photosensitizer i le tele o talosaga.
3. Antibacterial properties: Ona o ana mea antibacterial,oxide silivae faʻaaogaina i vailaʻau, aemaise lava o se mea faʻapipiʻi antibacterial mo mea faʻapitoa ma faʻaofuofu manuʻa.
4. Gaoioiga Catalytic:Silver oxidegalue e fai ma fa'alavelave i nisi fa'agaioiga kemikolo fa'aola.E mafai ona faʻaaogaina e fai ma faʻamalosi lagolago i le tele o gaioiga faʻapisinisi, e pei o faʻamaʻi faʻamaʻi.
I le faaiuga:
Silver oxideo lo'o fa'aauau pea ona fa'aofo tagata su'esu'e kemisi ma tagata su'esu'e i le lalolagi atoa i lona fausaga mole mole tulaga ese ma mea fa'afiafia.O leAg2OO le fua mole mole e fa'ailoa mai ai se tu'ufa'atasiga manaia o fa'amea siliva ma le okesene, e fa'atupuina ai se fa'afefiloi ma fa'aoga 'ese'ese, mai ata pu'e i vaila'au ma catalysis.
Malamalama i le kemisi i tuaoxide silivae le gata ina fa'amalieina ai lo tatou fia iloa ae fa'ata'ita'iina ai fo'i uiga lavelave o le fa'aputuga.O le isi taimi la e te fetaiai ai ma leAg2Ofua mole mole, manatua uiga mataʻina ma faʻaoga e fesoʻotaʻi ma le oxide siliva, o ia mea uma e mafua mai i le faʻatulagaina ma le faaeteete o atoma.
