Hobaneng sekhahla sa karabelo sasilicon'me sodium hydroxide e ka feta ea silicon dioxide e ka hlahlojoa ho tsoa likarolong tse latelang:
Phapang ea matla a bond ea lik'hemik'hale
▪ Tšebetso ea silicon le sodium hydroxide: Ha silicon e kopana le sodium hydroxide, matla a Si-Si pakeng tsa liathomo tsa silicon ke 176kJ/mol feela. Bond ea Si-Si e robeha nakong ea karabelo, e batlang e le bonolo ho e senya. Ho ea ka pono ea kinetic, karabelo e bonolo ho tsoela pele.
▪ Tsela eo silicon dioxide le sodium hydroxide e itšoarang ka eona: Matla a Si-O pakeng tsa liathomo tsa silicon le liathomo tsa oksijene ka silicon dioxide ke 460kJ/mol, e batlang e phahame. Ho nka matla a phahameng ho senya tlamo ea Si-O nakong ea karabelo, kahoo karabelo e batla e le thata ho etsahala 'me sekhahla sa karabelo se lieha.
Mekhoa e fapaneng ea ho itšoara
▪ Silicon e kopana le sodium hydroxide: Silicon e qala ka ho kopana le sodium hydroxide ka ho sebelisa metsi ho hlahisa hydrogen le silicic acid, ebe silicic acid e kopana le sodium hydroxide ho hlahisa sodium silicate le metsi. Nakong ea karabelo ena, karabelo lipakeng tsa silicon le metsi e ntša mocheso, o ka khothaletsang motsamao oa limolek'hule, ka hona ho theha tikoloho e ntle ea kinetic bakeng sa karabelo le ho potlakisa sekhahla sa karabelo.
▪ Silicon dioxide e kopana le sodium hydroxide: Silicon dioxide e qala ka ho kopana le sodium hydroxide pele ka metsi ho hlahisa asiti ea silicic, ebe silicic acid e kopana le sodium hydroxide ho hlahisa sodium silicate. Karabelo lipakeng 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 thuse ho arabela ka potlako.
Mehaho 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 batlang li fokola pakeng tsa liathomo, ho nolofalletsa tharollo ea sodium hydroxide ho kopana le ho itšoara ka liathomo tsa silicon.
▪ Sebopeho sasilicondioxide:silicondioxide e na le sebopeho sa marang-rang se tsitsitseng.Siliconeliathomo le liathomo tsa oksijene li tlanngoe ka thata ke li- covalent bonds ho theha sebopeho sa kristale se thata le se tsitsitseng. Ho thata hore tharollo ea sodium hydroxide e kenelle ka hare ho eona ebe e kopana ka botlalo le liathomo tsa silicon, e leng se bakang bothata ba ho arabela ka potlako. Ke liathomo tsa silicon feela tse holim'a likaroloana tsa silicon dioxide tse ka sebetsanang le sodium hydroxide, ho fokotsa sekhahla sa karabelo.
Phello ea maemo
▪ Tsela e silicon e nang le sodium hydroxide e sebetsang ka eona: Maemong a ho futhumatsa, lebelo la silicon le sodium hydroxide solution le tla potlakisa haholo, 'me ka kakaretso e ka tsoela pele hantle ha mocheso o le holimo.
▪ silicon dioxide e nang le sodium hydroxide e sebetsa butle haholo mochesong oa kamore. Hangata, sekhahla sa karabelo se tla ntlafatsoa tlasa maemo a thata joalo ka mocheso o phahameng le tharollo ea sodium hydroxide.
