Igama Lekhemikhali Le-Oxalic Acid
Igama Lekhemikhali Le-Oxalic Acid I-Oxalic acid, eyaziwa nangokuthi i-ethanedioic acid, iyinhlanganisela ye-crystalline organic engenambala enefomula yamakhemikhali i-H₂C₂O₄ kanye nokuncibilika okuhle emanzini. Njenge-organic acid, inezinhlobo eziningi zezicelo, okuhlanganisa ukufakelwa kwe-electroplating, ukuhlanza insimbi, kanye nodayi wezindwangu...Funda kabanzi -
Ukuphathwa Nokugcinwa Kwe-Oxalic Acid.
Isigaba 6: Ukuphathwa Nokugcinwa Kwe-Oxalic Acid Izinyathelo Zokuqapha Zokuphatha I-Oxalic Acid Zisebenza ohlelweni oluvaliwe olunomoya wokungenisa umoya wendawo. Abasebenzi kumele bathole ukuqeqeshwa okukhethekile futhi balandele ngokuqinile izinqubo zokusebenza. Kunconywa ukuthi abaqhubi bagqoke izifihla-buso zothuli (uhlobo olugcwele ubuso), umzimba ogcwele...Funda kabanzi -
Izinyathelo Zokukhululwa Ngengozi kwe-Oxalic Acid.
Isigaba 5: Ukukhishwa Ngengozi kwe-Oxalic Acid Kulinganisa Impendulo Ephuthumayo ye-Oxalic Acid: Hlukanisa indawo engcolile bese ukhawulela ukufinyelela. Nquma yonke imithombo yokushisa. Kunconywa ukuthi abasabela ezimweni eziphuthumayo bagqoke imaski yothuli (uhlobo oluphelele lobuso) kanye nezingubo zokuzivikela. Gwema ukuphakamisa uthuli; qaphela...Funda kabanzi -

Isigaba 4: Izindlela Zokulwa Nomlilo ze-Oxalic Acid Izakhiwo Eziyingozi ze-Oxalic Acid Iyasha uma ivezwa emalangabini avulekile noma ekushiseni okuphezulu. Iyabola lapho ifudumala ukuze ikhiqize amagesi anobuthi. Imikhiqizo Yokusha Eyingozi ye-Oxalic Acid I-Carbon monoxide, i-carbon dioxide. Izindlela Zokucisha ze-Oxalic Acid I-Firefig...Funda kabanzi -
Yiziphi izindlela zosizo lokuqala ze-oxalic acid?
Isigaba 3: Izinyathelo Zosizo Lokuqala ze-Oxalic acid I-Oxalic acid Ukuthintana Nesikhumba: Susa ngokushesha izingubo ezingcolile bese ugeza indawo ethintekile ngamanzi amaningi agobhozayo okungenani imizuzu eyi-15. Funa usizo lwezokwelapha. I-Oxalic acid Ukuthintana Namehlo: Phakamisa amehlo ngokushesha bese ugeza kahle iso...Funda kabanzi -
Ukuhlonza Umkhiqizo Wamakhemikhali we-Oxalic Acid.

Izindinganiso ze-Ethanol Yezimboni.
Izindinganiso Zokubukeka Nephunga Le-Ethanol Yezimboni Umkhiqizo kufanele ucace futhi ubonakale, ungabi nokungcola okubonakalayo. Akufanele ube nephunga elingavamile, ungabi nephunga elibukhali elibonakalayo, noma amanye amaphunga angajwayelekile. Izinkomba Zomzimba Nezamakhemikhali Okuqukethwe kwe-Ethanol (C₂H₅OH, ingxenye enkulu): ≥ 95.0% (premi...Funda kabanzi -
Yiziphi izinzuzo ze-ethanol njengomkhiqizo wokubulala amagciwane?
Imikhiqizo Yokubulala Amagciwane Utshwala olunengxenye yevolumu engaphezu kuka-99.5% lubizwa ngokuthi i-ethanol ephelele. Ku-biology, lusetshenziswa ngoba imibala ekwi-chloroplast iyancibilika ezinyibilikisini eziphilayo njenge-ethanol ephelele (noma i-acetone), ngakho-ke i-ethanol ephelele ingasetshenziswa ukukhipha lawa mabala. Utshwala obungu-95% busetshenziswa...Funda kabanzi -
Ukusetshenziswa kwe-Ethanol
Ukusetshenziswa kwe-Ethanol Izinto Zokusetshenziswa Ezingavuthiwe Zezimboni I-Ethanol inokusetshenziswa okubanzi kwezimboni, okuhlanganisa: Njenge-solvent; ekuhlanganisweni kwezinto eziphilayo; ukwenza ama-crystallization amakhemikhali ahlukahlukene; njenge-ejenti yokuhlanza kanye ne-extractant. Utshwala obudliwayo bungasetshenziswa ukuhlanganisa iziphuzo ezimhlophe, njenge-glue, kanye...Funda kabanzi -
I-ethanol inezinhlobo eziningi zezicelo.
I-Ethanol inezinhlobo eziningi zezicelo. Ingasetshenziswa ukukhiqiza i-acetic acid, iziphuzo, ukunambitheka, udayi, uphethiloli, nokuningi. Emkhakheni wezokwelapha, i-ethanol enengxenye yomthamo engu-70%–75% ivame ukusetshenziswa njengesibulali-magciwane. Iphinde isetshenziswe kakhulu ekuvikeleni kwezwe, embonini yamakhemikhali, kwezempilo...Funda kabanzi -
Kuyini i-Ethanol?
Kuyini i-Ethanol? I-Ethanol, eyaziwa kakhulu ngokuthi utshwala, iyinhlanganisela yezinto eziphilayo enefomula yesakhiwo i-CH₃CH₂OH (noma i-C₂H₅OH) kanye nefomula yama-molecule i-C₂H₆O. Iwutshwala obuvame kakhulu obuyi-monohydric. Emazingeni okushisa asekamelweni kanye nengcindezi, i-ethanol iwuketshezi olukhanyayo, oluguquguqukayo, olungenambala ...Funda kabanzi -
