IKHEMISTRI YESIKOLO SAMAPHAKATHI

Imibuzo Nengxoxo Yesibonelo Sezimpendulo Ze-Redox Isingeniso Sezimpendulo Ze-Redox Ukusabela kwe-redox (ukunciphisa-ukuxiliswa) kuyindlela yokusabela kwamakhemikhali lapho ama-electron edluliselwa khona phakathi kwezinhlobo ezimbili zamakhemikhali. Lokhu kusabela kuhilela izinguquko enanini le-oxidation lama-athomu ngaphakathi kwe-molecule, i-ion, noma i-compound. Igama elithi "redox" livela emiqondweni emibili: ukunciphisa kanye nokuxiliswa. Ukunciphisa inqubo lapho into... Funda kabanzi

Imibuzo eyisibonelo exoxa ngama-Electrolyte Aqinile, ama-Electrolyte Abuthakathaka, kanye nama-Non-electrolyte. Ama-Electrolyte angumqondo oyisisekelo kumakhemikhali obalulekile, ikakhulukazi ekufundweni kokusabela okubandakanya izixazululo. Ama-Electrolyte ayizinhlanganisela, lapho zincibilikiswa emanzini, ezikhiqiza ama-ion avumela isixazululo ukuthi siqhube ugesi. Ngokusekelwe ekhonweni lazo lokuhlukana zibe ama-ion, ama-electrolyte ahlukaniswe ngezigaba ezintathu... Funda kabanzi

Imibuzo Yesibonelo Sengxoxo Yama-Electrolyte Ama-Electrolyte ayizinto ezingaqhuba ugesi uma zincibilikiswa emanzini noma kwezinye izinyibilikisi. Ama-Electrolyte ahlukaniswe izinhlobo ezimbili eziyinhloko: ama-electrolyte aqinile nama-electrolyte abuthakathaka. Ama-electrolyte aqinile axutshwa ngokuphelele ne-ion kusisombululo, kuyilapho ama-electrolyte abuthakathaka exutshwa kancane ne-ion. Ama-electrolyte adlala indima ebalulekile ekusabeleni kwamakhemikhali ahlukahlukene kanye nokuphila kwansuku zonke. Kulesi sihloko… Funda kabanzi

Imibuzo Yokuxoxisana Nge-Electrochemistry: I-Electrochemistry iyigatsha le-chemistry elifunda ubudlelwano phakathi kokusabela kwamakhemikhali kanye noshintsho lwamandla kagesi. Ku-electrochemistry, kunemibono emibili eyinhloko: i-oxidation (ukukhululwa kwama-electron) kanye nokunciphisa (ukuzuza kwama-electron). Lezi zinqubo zingabonakala ezinhlotsheni ezimbili zamaseli e-electrochemical: amaseli e-voltaic (amaseli e-galvanic) namaseli e-electrolytic. Nazi ezinye izibonelo zemibuzo kanye... Funda kabanzi

Imibuzo Eyisibonelo kanye Nengxoxo Ngendlela Yokwenza Ama-Colloid Ama-Colloid ayingxube lapho izinhlayiya zesigaba esisodwa noma ngaphezulu zisatshalaliswa ngokulinganayo endaweni yokuhlakazeka. Ama-Colloid anezindlela ezahlukahlukene zokusetshenziswa empilweni yansuku zonke, kusukela ekudleni nasezimonyweni kuya kwezokwelapha nasezimbonini. Ukuze siqonde kangcono indlela yokwenza ama-colloid, ake siqale ngokuxoxa ngemibuzo ethile... Funda kabanzi

Imibuzo Yesibonelo Sengxoxo Yezakhiwo Ze-Colloidal Ama-Colloid awuhlobo lwengxube lapho into eyodwa ihlakazeka ngokulinganayo kwenye into. Lezi zinhlelo ezihlakazekile zinezinhlayiya ezinkulu kunezinhlayiya ezilula kodwa ezincane kunezinhlayiya eziqinile. Ama-Colloid anezakhiwo ezithile eziwahlukanisa nezixazululo zangempela kanye nezinhlayiya. Kulesi sihloko, si… Funda kabanzi

Imibuzo Yezibonelo Nengxoxo Yezinhlobo Zama-Colloids Isingeniso Ama-Colloids ayizinhlelo eziqukethe izigaba ezimbili: isigaba esihlakazekile kanye nesigaba sokuhlakazeka. Isigaba esihlakazekile yizinhlayiya ezinobukhulu be-colloidal (1-1000 nm), kanti isigaba sokuhlakazeka siyindlela lapho izinhlayiya zihlakazeka khona. Ama-Colloids avame ukuhlangana khona empilweni yansuku zonke futhi afundwa kumakhemikhali ngenxa yezakhiwo zawo... Funda kabanzi

Izinkinga Nengxoxo Yama-Colloidal: Ama-Colloidal ayizinhlelo lapho into eyodwa ihlakazeka khona ngokulinganayo kwenye into. Izinhlelo zama-Colloidal ziwela phakathi kwezindlela ezimbili ezihlukile: izixazululo zangempela kanye nokumiswa okuqinile. Ama-Colloid anezindlela eziningi zokusebenzisa empilweni yansuku zonke nasembonini, okwenza kube yisihloko esithakazelisayo sokutadisha kumakhemikhali. Lesi sihloko sizoxoxa ngezibonelo kanye… Funda kabanzi

Izinkinga Zesibonelo Ukuxoxa Ngokucindezelwa Kwe-Osmotic Kwezixazululo Isingeniso Ukucindezela kwe-Osmotic kuyinto ebalulekile kumakhemikhali kanye ne-biology. Kuyingcindezi edingekayo ukuvimbela ukugeleza kwamanzi kulwelwesi olungangeni kahle kusuka esixazululweni sokuhlushwa okuphansi kuya esixazululweni sokuhlushwa okuphezulu. Ukuqonda ingcindezi ye-osmotic kubalulekile ezindleleni ezahlukahlukene ezifana nezinqubo zebhayoloji kumaseli, ukwelashwa kwamanzi, ... Funda kabanzi

Imibuzo Yesibonelo kanye Nengxoxo Ngokuphakama Kwezixazululo Zezindawo Zokubilisa Isingeniso Ukuphakama kwezindawo zokubilisa kuyisenzakalo esihambisanayo esenzeka lapho i-solute ingezwa ku-solvent. Lesi simo sibhekisela ekwandeni kwephuzu lokubilisa lesisombululo uma kuqhathaniswa nephuzu lokubilisa le-solvent emsulwa. Kumakhemikhali, ukuqonda ukuphakama kwephuzu lokubilisa kubalulekile, ikakhulukazi esimweni sokusabela kwamakhemikhali, izinqubo zokuhlukanisa, … Funda kabanzi
