Kedu ihe kpatara mmeghachi omume nke Si na NaOH ji dị ngwa karịa SiO2?

Gịnị kpatara ọnụego mmeghachi omume nkesiliconna sodium hydroxide nwere ike karịa nke silicon dioxide nwere ike nyochaa site na akụkụ ndị a:

Ọdịiche dị na ike njikọ kemikal

▪ Mmeghachi omume nke silicon na sodium hydroxide: Mgbe silicon meghachiri omume na sodium hydroxide, ike njikọ Si-Si n'etiti atọm silicon bụ naanị 176kJ/mol. Njikọ Si-Si na-agbaji n'oge mmeghachi omume ahụ, nke dị mfe imebi. Site na echiche kinetic, mmeghachi omume dị mfe ịga n'ihu.

▪ Mmeghachi omume nke silicon dioxide na sodium hydroxide: Ike njikọ Si-O dị n’etiti atọm silicon na atọm oxygen dị na silicon dioxide bụ 460kJ/mol, bụ́ nke dịtụ elu. Ọ na-ewe ike dị elu iji mebie njikọ Si-O n'oge mmeghachi omume ahụ, ya mere mmeghachi omume siri ike ime na ọnụ ọgụgụ mmeghachi omume na-adị ngwa ngwa.

Usoro mmeghachi omume dị iche iche

▪ Silicon na-emeghachi omume na sodium hydroxide: Silicon na-emeghachi omume na sodium hydroxide nke mbụ site n'iji mmiri mee ihe iji mepụta hydrogen na silicic acid, e mesịa, silicic acid na-emeghachi omume na sodium hydroxide iji mepụta sodium silicate na mmiri. N'oge mmeghachi omume a, mmeghachi omume dị n'etiti silicon na mmiri na-ahapụ okpomọkụ, nke nwere ike ịkwalite mmegharị nke molekụla, si otú ahụ na-emepụta gburugburu kinetic ka mma maka mmeghachi omume na ngwa ngwa mmeghachi omume.

▪ Silicon dioxide na-emeghachi omume na sodium hydroxide: Silicon dioxide na-emeghachi omume na sodium hydroxide nke mbụ site n’iji mmiri mee ihe iji mepụta silicic acid, e mesịa, silicic acid na-emeghachi omume na sodium hydroxide iji mepụta sodium silicate. Mmeghachi omume n'etiti silicon dioxide na mmiri dị oke nwayọ, na usoro mmeghachi omume anaghị ahapụ okpomọkụ. Site na echiche nke kinetic, ọ naghị akwado mmeghachi omume ngwa ngwa.

Ụdị ihe dị iche iche

▪ Ọdịdị silicon:Silikoninwere usoro kristal ụfọdụ, ma enwere ụfọdụ oghere na mmekọrịta adịghị ike n'etiti atọm, na-eme ka ọ dịrị mfe maka ngwọta sodium hydroxide ịkpọtụrụ na meghachi omume na atom silicon.

▪ Ọdịdị nkesiliconmmiri ozuzo:silicondioxide nwere usoro netwọk ohere kwụsiri ike.SilikoniAtọm na ikuku oxygen na-ejikọta nke ọma site na njikọ covalent iji mepụta usoro kristal siri ike ma kwụsie ike. Ọ na-esiri ngwọta sodium hydroxide ike ịbanye n'ime ime ya wee kpọtụrụ atom silicon zuru oke, na-ebute ihe isi ike na mmeghachi omume ngwa ngwa. Naanị silicon atom dị n'elu mkpụrụ irighiri silicon dioxide nwere ike ime ya na sodium hydroxide, na-amachi ọnụego mmeghachi omume.

Mmetụta nke ọnọdụ

▪ Mmeghachi omume nke silicon na sodium hydroxide: N'okpuru ọnọdụ okpomọkụ, a ga-eme ka ọ̀tụ̀tụ̀ mmeghachi omume nke silicon na ngwọta sodium hydroxide dị ngwa ngwa, mmeghachi omume ahụ pụkwara ịga n'ihu n'ozuzu nke ọma na okpomọkụ dị elu.

▪ Mmeghachi omume nke silicon dioxide na sodium hydroxide: Mmeghachi omume nke silicon dioxide na sodium hydroxide ngwọta na-adị ngwa ngwa n'ime ụlọ okpomọkụ. Ọtụtụ mgbe, a ga-emeziwanye ọnụego mmeghachi omume n'okpuru ọnọdụ siri ike dị ka oke okpomọkụ na ngwọta sodium hydroxide.
