Gịnị kpatara ọnụego mmeghachi omume nke Si na NaOH ji dị ngwa karịa SiO2?

Gịnị kpatara ọnụego mmeghachi omume nkesilikọnEnwere ike inyocha sodium hydroxide site na akụkụ ndị a:

Ọdịiche dị na ike njikọ kemịkalụ

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

▪ Mmeghachi omume nke silicon dioxide na sodium hydroxide: Ike njikọ Si-O n'etiti atọm silicon na atọm oxygen dị na silicon dioxide bụ 460kJ/mol, nke dị elu karịa. Ọ na-ewe ike dị elu iji mebie njikọ Si-O n'oge mmeghachi omume ahụ, yabụ mmeghachi omume ahụ siri ike ime ma ọnụego mmeghachi omume ahụ na-adị nwayọ.

Usoro mmeghachi omume dị iche iche

▪ Silicon na-emeghachi omume na sodium hydroxide: Silicon na-emeghachi omume na sodium hydroxide site na imeghachi omume na mmiri iji mepụta hydrogen na silicic acid, mgbe ahụ 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-ewepụta okpomọkụ, nke nwere ike ịkwalite mmegharị molekul, si otú a na-emepụta gburugburu ebe obibi ka mma maka mmeghachi omume ahụ ma na-eme ka ọnụego mmeghachi omume dịkwuo ngwa ngwa.

▪ Silicon dioxide na-emeghachi omume na sodium hydroxide: Silicon dioxide na-emeghachi omume na sodium hydroxide mbụ site n'imeghachi omume na mmiri iji mepụta silicic acid, mgbe ahụ silicic acid na-emeghachi omume na sodium hydroxide iji mepụta sodium silicate. Mmeghachi omume dị n'etiti silicon dioxide na mmiri na-adị nwayọ nke ukwuu, usoro mmeghachi omume ahụ anaghị ewepụta okpomọkụ. Site n'echiche kinetic, ọ naghị akwalite mmeghachi omume ngwa ngwa.

Ọdịdị ihe dị iche iche

▪ Ọdịdị silikọn:Silikọnnwere ụfọdụ nhazi kristal, enwerekwa ụfọdụ oghere na mmekọrịta dị nro n'etiti atọm, nke na-eme ka ọ dịrị sodium hydroxide mfe ịkpọtụrụ ma meghachi omume na atọm silicon.

▪ Nhazi nkesilikọndaịọdịyọk:silikọndioxide nwere usoro netwọk oghere kwụsiri ike.SilikọnA na-ejikọta atọm na atọm oxygen nke ọma site na njikọ covalent iji mepụta usoro kristal siri ike ma kwụsie ike. Ọ na-esiri ike ka mmiri sodium hydroxide banye n'ime ya ma metụ atọm silicon aka nke ọma, nke na-ebute nsogbu na mmeghachi omume ngwa ngwa. Naanị atọm silicon dị n'elu ihe ndị dị na silicon dioxide nwere ike imeghachi omume na sodium hydroxide, na-ebelata ọnụego mmeghachi omume.

Mmetụta nke ọnọdụ

▪ Mmeghachi omume nke silicon na sodium hydroxide: N'ọnọdụ okpomọkụ, ọnụego mmeghachi omume nke silicon na sodium hydroxide ga-adị ngwa ngwa nke ukwuu, mmeghachi omume ahụ nwekwara ike ịga n'ihu nke ọma n'oge okpomọkụ dị elu.

▪ Mmeghachi omume nke silicon dioxide na sodium hydroxide: Mmeghachi omume nke silicon dioxide na sodium hydroxide na-adị nwayọ nwayọ n'ọnọdụ okpomọkụ ụlọ. Ọtụtụ mgbe, a ga-eme ka ọnụego mmeghachi omume ka mma n'ọnọdụ siri ike dịka oke okpomọkụ na ngwọta sodium hydroxide a chịkọtara.
