Ubucucike bwa acide acike: ubushishozi no gusesengura
Mu nganda zikora imiti, acide acetike ni imiti ikoreshwa cyane kandi ikomeye. Ku banyamwuga bakora mu rwego rwa shimi, gusobanukirwa imiterere yumubiri wa acide acetike, cyane cyane ubwinshi bwayo, ni ngombwa mugushushanya, gucunga neza no gutunganya neza. Muri iyi nyandiko, tuzasesengura ubwinshi bwa acide acetike kandi tunaganire ku ngaruka zayo no gutekereza kubikorwa bifatika.
Incamake yimiterere yibanze nubucucike bwa acide acike
Acide acetike (formulaire ya chimique: CH₃COOH), izwi kandi nka acide acike, ni aside kama ifite uburyohe bukomeye kandi impumuro mbi. Nkibikoresho byingenzi bya chimique, acide acetike ikoreshwa cyane mubice byinshi nkibiryo, imiti, nimiti. Ku bushyuhe bwicyumba (25 ° C), aside acike ifite ubucucike bwa 1.049 g / cm³. Agaciro kerekana ko aside irike iremereye gato mumazi yayo ugereranije namazi (ubucucike bwa 1 g / cm³).
Ingaruka yubushyuhe ku bwinshi bwa acide acike
Ubucucike, umutungo wingenzi wibintu, mubisanzwe uhinduka nubushyuhe. Ubucucike bwa acide acike nabwo ntibusanzwe. Ubushyuhe bugenda bwiyongera, ubushyuhe bwumuriro wa molekile ya acide ya acetike buragenda bwiyongera kandi intera ya molekile ikiyongera, bikavamo kugabanuka gahoro gahoro. Kurugero, kuri 40 ° C ubucucike bwa acide acike ni 1.037 g / cm³, mugihe kuri 20 ° C hafi ya 1.051 g / cm³. Uyu mutungo ni ingenzi cyane mubikorwa bifatika, cyane cyane mugihe cyo gufata neza no kugenzura neza, aho hagomba kwitabwaho ingaruka zubushyuhe ku bucucike bwa acide acike kugira ngo ibikorwa bigende neza kandi byiza.
Akamaro ka acide acike mubikorwa byinganda
Mubikorwa byo gutunganya imiti, ubwinshi bwa acide acetike ntabwo bugira ingaruka kububiko bwayo no kuyitwara gusa, ahubwo bifitanye isano itaziguye nigipimo cyibikorwa n'imikorere y'ibicuruzwa. Mugutegura ibisubizo, ubumenyi nyabwo bwubucucike bwa acide acetike bufasha kumenya igipimo nyacyo cya solute na solvent, bityo bigahindura imiterere yimikorere. Mugihe cyo kubika no gutwara, ubucucike nikintu cyingenzi muguhitamo ubushobozi nubushobozi bwo gutwara ibintu kugirango umutekano ube mwiza nubukungu.
Ibipimo bya acide acike hamwe nibipimo
Mu nganda, ubucucike bwa acide ya acetike busanzwe bupimishwa hifashishijwe ibikoresho nk'amacupa yihariye ya gravit, ubwoko bwa gravimetre-float cyangwa vibrating tube densitometero. Ibi bipimo bituma ubwinshi bwa acide acetike bugenwa neza kandi bugakoreshwa mugucunga ubuziranenge no gukora neza. Ibipimo mpuzamahanga byubucucike bwa acide acetike mubisanzwe bishingiye kugenzura neza ubushyuhe, bityo ihindagurika ryubushyuhe naryo ryibanze mugihe cyo gupima.
Incamake
Ubucucike bwa acide acike, nkimwe mumiterere yumubiri, bigira ingaruka zikomeye mubikorwa byinshi mu nganda zikora imiti. Binyuze mu gusobanukirwa byimbitse no gupima neza ubwinshi bwa acide acike, inzira yumusaruro irashobora kugenzurwa neza, ubwiza bwibicuruzwa burashobora kunozwa, kandi umutekano wububiko nubwikorezi urashobora kuboneka. Haba mubushakashatsi bwa laboratoire cyangwa mu nganda, imicungire yubucucike bwa acide ni igice cyingenzi kugirango imikorere yimiti igende neza.
Binyuze mu isesengura ryavuzwe haruguru, dushobora kubona neza ko gusobanukirwa no kumenya ubwinshi bwa acide acike bidafasha gusa kunoza umusaruro, ahubwo binagabanya imyanda nigiciro, bityo twifashisha amarushanwa akaze ku isoko.
