Isigaba 6: Ukuphathwa nokugcinwa kwe-Oxalic Acid Iinqabo zokuPhathwa kwe-Oxalic Acid Sebenzisa erherhweni elivaliweko elinokukhipha umoya wendawo. Abasebenzi kufanele bathole ukubandulwa okukhethekileko begodu balandele ngokuqinileko iinkambiso zokusebenza. Kunconywa bona abasebenzisi bagqoke iimaski zothuli (ubuso obupheleleko), umzimba woke...Funda kabanzi -
Iindlela zokukhutjhwa kwe-Oxalic Acid.
Isigaba 5: Iindlela zokukhutjhwa kwe-Oxalic Acid ngokungakalungi Ukuphendula okuphuthumako: Hlukanisa indawo engcolileko begodu uvimbele ukufikelela. Sika yoke imithombo yokuvutha. Kunconywa bona abaphenduli bezehlakalo eziphuthumako bagqoke iimaski zothuli (umhlobo wobuso obuzeleko) kanye nezambatho zokuzivikela. Balekela ukuphakamisa ithuli; ngokutjheja s...Funda kabanzi -
Iindlela zokulwisana nomlilo nge-Oxalic Acid.
Isigaba 4: Iindlela zokulwisana nomlilo nge-Oxalic Acid Iimpawu eziyingozi Ivutha lokha nayivezwa emalangabini avulekileko nofana emtjhisweni omkhulu. Iyabola lokha nayifuthumeleko ukukhiqiza amagesi anobuthi. I-Oxalic Acid Imikhiqizo Yokuvutha Eyingozi Ikhabhoni monokisayidi, ikhabhoni dioksayidi. Iindlela zokucima i-Oxalic Acid Umlilo...Funda kabanzi -
Ngiziphi iindlela zokusiza zokuthoma nge-oxalic acid?
Isigaba 3: I-Oxalic acid Iindlela zokusiza kokuthoma I-oxalic acid Ukuthintana nesikhumba: Susa msinyana izambatho ezisilapheleko bese uhlanza indawo ethintekileko ngamanzi amanengi okungenani imizuzu eli-15. Funa isizo lezokwelapha. I-oxalic acid Ukuthintana kwamehlo: Phakamisa amajwabu amehlo msinyana bese uhlanza amehlo kuhle...Funda kabanzi -
Ukukhonjwa komkhiqizo wamakhemikhali we-Oxalic Acid.
I-Oxalic Acid – Iphepha leDatha yokuPhepha (SDS) Isigaba 1: Ukukhonjwa komkhiqizo wamakhemikhali Ibizo le-China: I-Ethanedioic Acid Isifaniso: I-Oxalic Acid I-Oxalic Acid Ifomula yamamolekyuli: C₂H₂O₄ Ubunzima bamamolekhyuli: 90.04 Isigaba 2: Ubungozi be-Oxalic Acid I-Oxalic Acid i-asidi iyacasula khulu ...Funda kabanzi -
Amazinga we-Ethanol yamabubulo.
Amazinga wokubukeka kwe-Ethanol yamabubulo nephunga Umkhiqizo kufanele ube ngokukhanyako begodu ube sobala, ungabi nokusilaphazeka okubonakalako. Akukafaneli bona ibe nephunga elingakajayeleki, lingabi nephunga elibukhali, nofana amanye amaphunga angakavami. Iinkomba eziphathekako nezamakhemikhali Okuqukethwe kwe-ethanol (C₂H₅OH, ingcenye yesisindo): ≥ 95.0% (premi...Funda kabanzi -
Ngiziphi iinzuzo ze-ethanol njengomkhiqizo wokubulala amagciwane?
Imikhiqizo yokubulala amagciwane Utjwala obunomthamo ongaphezu kwama-99.5% bubizwa ngokuthi yi-ethanol epheleleko. Ku-biology, isetjenziswa ngombana ama-pigment ema-chloroplasts ancibilika eentweni eziphilako ezifana ne-ethanol epheleleko (nofana i-acetone), ngalokho i-ethanol epheleleko ingasetjenziselwa ukukhipha ama-pigment la. Utjwala obungu-95% busetjenziswa...Funda kabanzi -
Ukusetjenziswa kwe-Ethanol
Ukusetjenziswa kwe-Ethanol Iinsetjenziswa ezisetjenziswa emabubulweni I-Ethanol ineendlela ezinengi ezisetjenziswa emabubulweni, okufakahlangana: Njengesisombululo; ekuhlanganisweni kwezinto eziphilako; ukwenza amakristalu wamakhompawundi ahlukahlukeneko; njengesisetjenziswa sokuhlanza nesikhupha. Utjwala obudliwako bungasetjenziselwa ukuhlanganisa utjwala obumhlophe, njengesinamatheli, begodu njengento...Funda kabanzi -
I-ethanol ineendlela ezinengi zokusetjenziswa.
I-ethanol ineendlela ezinengi zokusetjenziswa. Ingasetjenziselwa ukukhiqiza i-acetic acid, iinselo, amafleyiva, amadayi, amafutha, nokunye. Emkhakheni wezokwelapha, i-ethanol enengcenye yevolumu engu-70% ukuya ku-75% ivamise ukusetjenziswa njengesibulala-magciwane. Iphinde isetjenziswe khulu ekuvikeleni inarha, embonini yamakhemikhali, ezepilo...Funda kabanzi -
Khuyini i-Ethanol?
Khuyini i-Ethanol? I-ethanol, eyaziwa ngokuthi yi-alcohol, yi-organic compound enefomula yesakhiwo CH₃CH₂OH (nofana C₂H₅OH) kanye nefomula yamamolekhyuli C₂H₆O. Yilo utjwala obuvame khulu obune-monohydric. Emazingeni womtjhiso wegumbi negandeleleko, i-ethanol yinto etjhisako, evuthako, engenambala ekhanyako ...Funda kabanzi -
