Kuki igipimo cya reaction ya Si na NaOH cyihuta kuruta SiO2?

Impamvu igipimo cya reaction yasiliconhydroxide ya sodium irashobora kurenza iya dioxyde ya silicon irashobora gusesengurwa mubice bikurikira:

Itandukaniro mu mbaraga zihuza imiti

▪ Imyitwarire ya hydroxide ya silicon na sodium: Iyo silicon ikora hamwe na hydroxide ya sodium, ingufu za Si-Si hagati ya atome ya silicon ni 176kJ / mol gusa. Inkunga ya Si-Si iracika mugihe cyo kubyitwaramo, byoroshye gucika. Duhereye kuri kinetic, reaction iroroshye gukomeza.

▪ Imyitwarire ya dioxyde ya silicon na hydroxide ya sodium: Ingufu za Si-O zihuza atome ya silicon na atome ya ogisijeni muri dioxyde de silicon ni 460kJ / mol, ikaba iri hejuru cyane. Bisaba imbaraga nyinshi kugirango ucike Si-O mugihe cyo kubyitwaramo, reaction rero iragoye kuboneka kandi igipimo cyitinda kiratinda.

Uburyo butandukanye bwo kubyitwaramo

▪ Silicon ikora hamwe na hydroxide ya sodium: Silicon ikora na hydroxide ya sodium ibanza gufata amazi kugirango ikore hydrogène na acide silicike, hanyuma aside silicike ikora hamwe na hydroxide ya sodium kugirango itange sodium silike namazi. Muri iki gisubizo, reaction iri hagati ya silicon namazi irekura ubushyuhe, bushobora guteza imbere molekile, bityo bigatuma habaho ibidukikije byiza bya reaction kandi byihutisha umuvuduko.

Oxy Dioxyde ya Silicon ikora hamwe na hydroxide ya sodium: Dioxyde ya Silicon ikora mbere na hydroxide ya sodium ibanza gufata amazi kugirango ikore aside silike, hanyuma aside silicike ikora hamwe na hydroxide ya sodium kugirango ikore sodium silike. Imyitwarire hagati ya dioxyde de silicon namazi iratinda cyane, kandi inzira yo kubyitwaramo ntabwo irekura ubushyuhe. Duhereye kuri kinetic, ntabwo bifasha reaction yihuse.

Imiterere itandukanye

Structure Imiterere ya Silicon:Siliconifite imiterere ya kristu, kandi hariho icyuho runaka nubusabane bugereranije hagati ya atome, byorohereza igisubizo cya sodium hydroxide guhura no gukora hamwe na atome ya silicon.

Imiterere yasilicondioxyde:silicondioxyde ifite imiterere ihamye yumurongo.Siliconatom na ogisijeni atome ihujwe cyane na covalent bonds kugirango ikore ibintu bikomeye kandi bihamye. Biragoye ko igisubizo cya sodium hydroxide cyinjira mumbere yacyo kandi kigahura neza na atome ya silicon, bikaviramo ingorane zo kwihuta. Gusa atomike ya silicon hejuru yubutaka bwa dioxyde de silicon irashobora kwitwara hamwe na hydroxide ya sodium, bikagabanya igipimo cyibisubizo.

Ingaruka yimiterere

▪ Imyitwarire ya silicon hamwe na hydroxide ya sodium: Mugihe cyubushyuhe, igipimo cya silicon hamwe nigisubizo cya sodium hydroxide kizihuta cyane, kandi reaction irashobora kugenda neza mubushyuhe bwinshi.

▪ Imyitwarire ya dioxyde ya silicon hamwe na hydroxide ya sodium: Imyitwarire ya dioxyde ya silicon hamwe numuti wa sodium hydroxide itinda cyane mubushyuhe bwicyumba. Mubisanzwe, igipimo cyibisubizo bizanozwa mubihe bigoye nkubushyuhe bwo hejuru hamwe na sodium hydroxide yibanze.
