E noʻonoʻo i ke kumuoxide kalahōʻike ʻia ʻo ia e ke ʻano kemika Ag2O?Pehea i hana ʻia ai kēia hui?Pehea ka ʻokoʻa me nā ʻokikene metala ʻē aʻe?Ma kēia moʻomanaʻo, e ʻimi mākou i ke kemika hoihoi ooxide kalaa hōʻike i nā kumu ma hope o kona ʻano molekala kū hoʻokahi.
E aʻo e pili anaoxide kala:
ʻOkika kala (Ag2O)he pūhui kino ʻole i haku ʻia me nā ʻātoma kala (Ag) a me ka oxygen (O).Ma muli o kona ʻano kumu, ua hoʻokaʻawale ʻia ʻo ia ma ke ʻano he oxide kumu.Akā, no ke aha i kapa ʻia ai ʻo Ag2O?E ʻeli kākou i kona hoʻokumu ʻana e ʻike ai.
Ka hookumu ana ooxide kala:
Hoʻokumu mua ʻia ka ʻokikene kālā ma o ka hopena ma waena o ke kālā a me ka oxygen.Ke hoʻopili ʻia ke metala kālā me ka ea, hiki ke kaʻina hana hoʻokahe lohi, hana ʻiaoxide kala.
2Ag + O2 → 2Ag2O
ʻOi aku ka maʻalahi o kēia pane ʻana i ka wā i hoʻomehana ʻia, e ʻae ana i nā ʻātoma kālā e hana maikaʻi loa me nā molekole oxygen, i ka hopena.oxide kala.
ʻAno molekole kū hoʻokahi:
ʻO ke kumu molekalaAg2Oe hōʻike ana he ʻelua ʻātoma kala i hoʻopaʻa ʻia i ka ʻātoma oxygen hoʻokahi.ʻO ka loaʻa ʻana o nā ʻātoma kālā ʻelua e hāʻawi i ka ʻokikene kālā i kahi stoichiometry kūʻokoʻa e hoʻokaʻawale iā ia mai nā mea ʻokikene metala ʻē aʻe.
ʻOkika kalahoʻohana i kahi ʻano kristal kūikawā i kapa ʻia ʻo inverse fluorite, ʻo ia ka mea kūʻē i ka ʻano fluorite maʻamau.I loko o ka hana antifluorite, hoʻokumu nā ʻātoma oxygen i kahi pūʻulu pili kokoke, aʻo nā ion kālā e noho ana i nā kūlana interstitial tetrahedral i loko o ka lattice kristal oxygen.
Nā hiʻohiʻona a me nā noi:
ʻOkika kalaloaʻa i kekahi mau waiwai hoihoi e waiwai ai ia ma nā ʻano ʻokoʻa.Eia kekahi mau hiʻohiʻona kaulana:
1. ʻAkala:ʻOkika kalaua manaʻo ʻia he pūhui alkaline a hōʻike i nā waiwai alkaline ke hoʻoheheʻe ʻia i loko o ka wai, e like me nā oxide metala ʻē aʻe.
2. Photosensitivity:ʻOkika kalahe kiʻi paʻi kiʻi, ʻo ia hoʻi ke loaʻa i kahi hopena kemika ke ʻike ʻia i ka mālamalama.Ua alakaʻi kēia waiwai i kona hoʻohana ʻana i nā kiʻiʻoniʻoni kiʻi a ma ke ʻano he photosensitizer i nā ʻano noi like ʻole.
3. Nā waiwai antibacterial: Ma muli o kāna mau waiwai antibacterial,oxide kalahoʻohana ʻia i ka lāʻau lapaʻau, ʻoi aku hoʻi ma ke ʻano he antibacterial coating no nā mea hana ʻoki a me nā ʻaʻahu ʻeha.
4. Ka hana catalytic:ʻOkika kalahana ma ke ʻano he mea hoʻoheheʻe i kekahi mau hoʻoheheʻe kemika.Hiki ke hoʻohana ʻia ma ke ʻano he kākoʻo catalyst i nā kaʻina hana ʻoihana, e like me nā hopena oxidation.
I ka hopena:
ʻOkika kalaKe hoʻomau nei ka hoʻonanea ʻana i nā chemists a me nā mea noiʻi ma ka honua holoʻokoʻa me kona ʻano molekala kū hoʻokahi a me nā waiwai hoihoi.ʻO kaAg2OHōʻike ka molecular formula i kahi hui hoihoi o nā ʻātoma kala a me ka oxygen, e hana ana i kahi hui me nā ʻano hoʻohana like ʻole, mai ke kiʻi a hiki i ka lāʻau lapaʻau a me ka catalysis.
ʻO ka hoʻomaopopo ʻana i ke kemika ma hopeoxide kalaʻaʻole wale e hoʻomāʻona i ko mākou ʻike akā hōʻike pū i nā waiwai paʻakikī o ka hui.No laila i ka manawa aʻe e hālāwai ai ʻoe me kaAg2Omolecular formula, e hoʻomanaʻo i nā waiwai kupaianaha a me nā noi e pili ana i ka ʻokikene kālā, nā hopena a pau ma muli o ka hoʻonohonoho pono ʻana o nā mana.
