Sei chiyero chemhinduro cheSi neNaOH chichikurumidza kupfuura SiO2?

Sei chiyero chekupindura kwesiliconuye sodium hydroxide inogona kupfuura iyo yesilicon dioxide inogona kuongororwa kubva pane zvinotevera:

Musiyano musimba rezvisungo zvemakemikari

▪ Kuita kwesilicon nesodium hydroxide: Kana silicon ikapindirana nesodium hydroxide, simba reSi-Si bond riri pakati pemaatomu esilicon rinongori 176kJ/mol. Si-Si bond inotyoka panguva yekuita, izvo zviri nyore kutyoka. Kubva pakuona kwekinetic, kuita kuri nyore kuenderera mberi.

▪ Kuita kwesilicon dioxide nesodium hydroxide: Simba reSi-O bond riri pakati pemaatomu esilicon nemaatomu eokisijeni musilicon dioxide i460kJ/mol, iyo yakakwira zvakanyanya. Zvinoda simba rakawanda kuti pave neSi-O bond panguva yekuita, saka kuita kwacho kwakaoma uye chiyero chekuita kwacho chinononoka.

Maitiro akasiyana ekuita

▪ Silicon inopindirana ne sodium hydroxide: Silicon inotanga yapindirana ne sodium hydroxide nemvura kuti igadzire hydrogen ne silicic acid, uye silicic acid inopindirana ne sodium hydroxide kuti igadzire sodium silicate nemvura. Munguva iyi, mafambiro ari pakati pe silicon nemvura anoburitsa kupisa, izvo zvinogona kukurudzira kufamba kwemamorekuru, nokudaro zvichigadzira nzvimbo iri nani ye kinetic yemhinduro uye kukurumidzisa reaction rate.

▪ Silicon dioxide inopindirana ne sodium hydroxide: Silicon dioxide inotanga yapindirana ne sodium hydroxide nemvura kuti igadzire silicic acid, uye silicic acid inopindirana ne sodium hydroxide kuti igadzire sodium silicate. Kuita pakati pe silicon dioxide nemvura kunonoka zvikuru, uye maitiro ekuita haaburitse kupisa. Kubva pakuona kwe kinetic, hazvibatsiri kuti pave nekukasira.

Zvivako zvakasiyana-siyana zvezvinhu

▪ Maumbirwo esilicon:Sirikiine chimiro chakati chekristaro, uye pane mipata yakati wandei uye kusashanda zvakanaka pakati pemaatomu, zvichiita kuti zvive nyore kuti sodium hydroxide solution ibatane uye iite nemaatomu esilicon.

▪ Maumbirwo esilicondhayiokisijeni:silicondiokisijeni ine chimiro chakasimba che network yenzvimbo.Sirikimaatomu nemaatomu eokisijeni zvakabatana zvakasimba ne covalent bonds kuti zvigadzire chimiro chekristaro chakasimba uye chakasimba. Zvakaoma kuti sodium hydroxide solution ipinde mukati mayo yobata maatomu esilicon zvizere, zvichikonzera kuoma kwekuita nekukurumidza. Maatomu esilicon chete ari pamusoro pezvikamu zvesilicon dioxide ndiwo anogona kuita ne sodium hydroxide, zvichideredza kumhanya kwekuita.

Mhedzisiro yemamiriro ezvinhu

▪ Kuita kwesilicon ne sodium hydroxide: Kana zvinhu zvichidziya, mwero wekuita kwesilicon ne sodium hydroxide solution uchakurumidza zvikuru, uye kuita kwese kunogona kufamba zvakanaka kana tembiricha yakakwira.

▪ Kuita kwesilicon dioxide ne sodium hydroxide: Kuita kwesilicon dioxide ne sodium hydroxide solution kunononoka zvikuru patembiricha yemumba. Kazhinji, kumhanya kwekuita kunovandudzwa mumamiriro ezvinhu akaoma akadai sekupisa kwakanyanya uye sodium hydroxide solution yakasimba.
