Sei maitiro ekuita kweSi neNaOH achikurumidza kupfuura SiO2?

Sei mhinduro rate yesiliconuye sodium hydroxide inogona kupfuura iyo yesilicon dioxide inogona kuongororwa kubva pane zvinotevera zvinhu:

Kusiyana kwemakemikari bond simba

▪ Kuita kwesilicon uye sodium hydroxide: Kana silicon ikasangana nesodium hydroxide, simba reSi-Si pakati pemaatomu esilicon rinongoita 176kJ/mol. Iyo Si-Si bond inoputika panguva yekuita, izvo zviri nyore kutyora. Kubva pane kinetic maonero, maitiro ari nyore kuenderera.

▪ Kuita kwesilicon dioxide uye sodium hydroxide: Simba reSi-O riri pakati pemaatomu esilicon nemaatomu eokisijeni musilicon dioxide i460kJ/mol, iyo yakati kurei. Zvinotora simba rakakwirira kuputsa chisungo cheSi-O panguva yekuita, saka maitiro acho akaoma kuitika uye chiyero chekuita chinononoka.

Maitiro akasiyana ekuita

▪ Silikoni inopindirana nesodium hydroxide: Silikoni inopindirana nesodium hydroxide inotanga yasangana nemvura kuti ibudise hydrogen uye silicic acid, ipapo silicic acid inopindirana nesodium hydroxide kuti ibudise sodium silicate nemvura. Munguva iyi yekuita, kuita pakati pesilicon nemvura kunoburitsa kupisa, izvo zvinogona kusimudzira kufamba kwema molecular, nekudaro zvichigadzira iri nani kinetic nharaunda yekuita uye nekumhanyisa chiyero chekuita.

▪ Silicon dioxide inopindirana nesodium hydroxide: Silicon dioxide inopindirana nesodium hydroxide inotanga yasangana nemvura kuti ibudise silicic acid, yozoita silicic acid inosanganidzana nesodium hydroxide kuti ibudise sodium silicate. Kuita pakati pesilicon dioxide nemvura kunononoka zvakanyanya, uye maitiro ekuita haasunungure kupisa. Kubva pakuona kwekinetic, haibatsiri kukurumidza kuita.

Zvimiro zvezvinhu zvakasiyana

▪ Silicon chimiro:Siliconine chimwe chimiro chekristaro, uye kune mamwe magaba uye kupindirana kusina kusimba pakati peatomu, zvichiita kuti zvive nyore kune sodium hydroxide solution kubata uye kuita nemaatomu esilicon.

▪ Chimiro chesilicondiokisi:silicondiokisi ine yakagadzikana spatial network chimiro.Siliconmaatomu uye maatomu eokisijeni zvakasungwa zvakasimba nemabhondi akabatana kuti aumbe chimiro chekristaro chakaoma uye chakatsiga. Zvakaoma kuti sodium hydroxide solution ipinde mukati mayo uye inyatsobata maatomu esilicon, zvichikonzera kuoma kwekukurumidza kuita. Chete maatomu esilicon ari pamusoro pesilicon dioxide particles anogona kuita ne sodium hydroxide, achidzikamisa chiyero chekuita.

Mhedzisiro yemamiriro

▪ Kuita kwesilicon ine sodium hydroxide: Mumamiriro ekupisa, mwero wesilicon ine sodium hydroxide solution uchakurumidzisa zvakanyanya, uye kuita kunogona kuenderera mberi zvakanaka pakupisa kwakanyanya.

▪ Kuita kwesilicon dioxide nesodium hydroxide: Kuita kwesilicon dioxide nesodium hydroxide solution kunonoka zvikuru kana paine tembiricha. Kazhinji, mwero wekuita unozovandudzwa pasi pemamiriro akaomarara senge tembiricha yakanyanya uye yakadzika sodium hydroxide mhinduro.
