Ke hobane'ng ha sekhahla sa karabelo ea Si le NaOH se potlakile ho feta SiO2?

Hobaneng sekhahla sa karabelo easiliconle sodium hydroxide e ka feta ea silicon dioxide e ka hlahlojoa ho tsoa lintlheng tse latelang:

Phapang matla a tlamo ea lik'hemik'hale

▪ Karabelo ea silicon le sodium hydroxide: Ha silicon e arabela le sodium hydroxide, matla a khokahano ea Si-Si pakeng tsa liathomo tsa silicon ke 176kJ/mol feela. Kamano ea Si-Si ea robeha nakong ea karabelo, e leng ntho e bonolo ho e roba. Ho ea ka pono ea kinetic, karabelo e bonolo ho tsoela pele.

▪ Karabelo ea silicon dioxide le sodium hydroxide: Matla a khokahano ea Si-O pakeng tsa liathomo tsa silicon le liathomo tsa oksijene ka har'a silicon dioxide ke 460kJ/mol, e leng se phahameng haholo. Ho hlokahala matla a mangata ho roba khokahano ea Si-O nakong ea karabelo, kahoo karabelo e thata ho etsahala 'me sekhahla sa karabelo se lieha.

Mekhoa e fapaneng ea karabelo

▪ Silicon e arabela le sodium hydroxide: Silicon e arabela le sodium hydroxide pele ka ho arabela le metsi ho hlahisa haedrojene le silicic acid, ebe silicic acid e arabela le sodium hydroxide ho hlahisa sodium silicate le metsi. Nakong ena ea karabelo, karabelo pakeng tsa silicon le metsi e ntša mocheso, e leng se ka khothalletsang motsamao oa limolek'hule, ka hona ho theha tikoloho e betere ea kinetic bakeng sa karabelo le ho potlakisa sekhahla sa karabelo.

▪ Silicon dioxide e arabela le sodium hydroxide: Silicon dioxide e arabela le sodium hydroxide pele ka ho arabela le metsi ho hlahisa silicic acid, ebe silicic acid e arabela le sodium hydroxide ho hlahisa sodium silicate. Karabelo pakeng tsa silicon dioxide le metsi e lieha haholo, 'me ts'ebetso ea karabelo ha e lokolle mocheso. Ho ea ka pono ea kinetic, ha e khothalletse karabelo e potlakileng.

Meaho e fapaneng ea thepa

▪ Sebopeho sa silicon:Siliconee na le sebopeho se itseng sa kristale, 'me ho na le likheo tse itseng le likamano tse fokolang pakeng tsa liathomo, e leng se etsang hore ho be bonolo hore tharollo ea sodium hydroxide e kopane le liathomo tsa silicon.

▪ Sebopeho sasilicondiokside:silicondiokside e na le sebopeho se tsitsitseng sa marangrang a sebaka.SiliconeLiathomo le liathomo tsa oksijene li tlamiloe ka thata ke litlamo tsa covalent ho theha sebopeho sa kristale se thata le se tsitsitseng. Ho thata hore tharollo ea sodium hydroxide e kenelle kahare ho eona 'me e kopane ka botlalo le liathomo tsa silicon, e leng se fellang ka bothata ba karabelo e potlakileng. Ke liathomo tsa silicon feela tse holim'a likaroloana tsa silicon dioxide tse ka arabelang le sodium hydroxide, e leng se fokotsang sekhahla sa karabelo.

Phello ea maemo

▪ Karabelo ea silicon ka sodium hydroxide: Tlas'a maemo a ho futhumatsa, sekhahla sa karabelo ea silicon ka tharollo ea sodium hydroxide se tla potlakisoa haholo, 'me karabelo e ka tsoela pele hantle mochesong o phahameng.

▪ Karabelo ea silicon dioxide ka sodium hydroxide: Karabelo ea silicon dioxide ka sodium hydroxide e lieha haholo mochesong oa kamore. Hangata, sekhahla sa karabelo se tla ntlafala tlas'a maemo a thata a kang mocheso o phahameng le tharollo ea sodium hydroxide e matlafetseng.
