IKHEMISTRI YESIKOLO SAMAPHAKATHI

Imibuzo Eyisibonelo Exoxa Nge-pH Yama-Acid Aqinile Nezisekelo Eziqinile. I-pH, noma amandla e-hydrogen, iyisilinganiso se-acidity noma i-alkalinity yesisombululo. Isikali se-pH sisukela ku-0 kuya ku-14, izinombolo ezingaphansi kuka-7 zibonisa isisombululo se-acidic, izinombolo ezingaphezu kuka-7 zibonisa isisombululo esiyisisekelo, kanye no-7 zibonisa isisombululo esingathathi hlangothi. Kulesi sihloko, sizoxoxa… Funda kabanzi

Imibuzo Eyisibonelo Exoxa Nge-acid kanye ne-base pH Uma sikhuluma ngama-acid kanye nezisekelo, umqondo owodwa obalulekile okumele siwuqonde yi-pH. I-pH iyisilinganiso se-acidity noma i-alkalinity yesisombululo. Ifomula eyodwa esetshenziswa ukunquma i-pH yile: \[ \text{pH} = -\log [H^+] \] Kule fomula, \([H^+]\) ukuhlushwa kwama-ion e-hydrogen ku … Funda kabanzi

Izinkinga Zesibonelo Samandla E-asidi Nesisekelo Amandla e-asidi nesisekelo yimibono ebalulekile kumakhemikhali ekhombisa ukuthi i-asidi noma i-molecule yesisekelo inganikela kanjani nge-proton (H⁺) noma yamukele i-proton, ngokulandelana. Kule ngxoxo, sizobheka izibonelo eziningana zezinkinga ezizosisiza siqonde amandla e-asidi nesisekelo, kanye nendlela yokubala i-pH ne-pOH yazo. … Funda kabanzi

Izinkinga Zamandla Nesisekelo Se-Acid Amandla nesisekelo se-pH yizihloko ezibalulekile kumakhemikhali, ikakhulukazi emkhakheni wama-acid nama-base. Kulesi sihloko, sizoxoxa ngendlela yokuthola amandla e-acid nesisekelo bese sibala i-pH yesisombululo sisebenzisa izibonelo eziningana zezinkinga ezinikeziwe. Isingeniso kuma-Acid kanye … Funda kabanzi

Imibuzo Nengxoxo Yesibonelo Se-Lewis Acid-Base Isingeniso Ukusabela kwe-acid-base kuyisihloko esiyisisekelo kukhemistri, esisetshenziswa kabanzi emikhakheni eyahlukene kanye nasezimbonini. Izincazelo eziningana zama-acid kanye nezisekelo zisetshenziswa kukhemistri, kufaka phakathi izincazelo ze-Arrhenius, i-Bronsted-Lowry, kanye ne-Lewis. Lesi sihloko sizogxila emqondweni wama-acid kanye nezisekelo ze-Lewis kanye… Funda kabanzi

Isibonelo Senkinga Yesisekelo Se-Acid EsiseBrønsted-Lowry Ama-asidi nezisekelo kuyimibono ebalulekile kumakhemikhali eye yathuthukiswa futhi yahlungwa ososayensi abaningi eminyakeni edlule. Enye yezinkolelo-mbono ezithandwa kakhulu yithiyori kaBrønsted-Lowry, eyaphakanyiswa nguJohannes Nicolaus Brønsted noThomas Martin Lowry ngo-1923. Le thiyori inikeza umbono obanzi wokuthi kanjani… Funda kabanzi

Imibuzo Nezingxoxo Zesibonelo Se-Arrhenius Acid-Base Ama-asidi nezisekelo kuyimibono eyisisekelo kumakhemikhali. Enye yemibono eyaziwayo kakhulu yokuchaza ukuziphatha kwama-asidi nezisekelo ithiyori ye-Arrhenius. Ngokusho kwe-Arrhenius, i-asidi iyinhlanganisela ethi, uma incibilikiswa emanzini, ikhiqize ama-ion e-H⁺ (noma i-H₃O⁺), kuyilapho isisekelo siyinhlanganisela ethi, uma incibilikiswa emanzini, ikhiqize… Funda kabanzi

Imibuzo Eyisibonelo Exoxa Ngezakhiwo Nemiqondo Yama-Acid Nezisekelo Izakhiwo nemibono yama-asidi nezisekelo ziyizihloko ezibalulekile kukhemistri, kanye nokusetshenziswa okubanzi emikhakheni eyahlukahlukene, okuhlanganisa imboni, ikhemisi, kanye ne-biochemistry. Ukuqonda imiqondo eyisisekelo kanye nokusetshenziswa kwezakhiwo ze-asid-base kubalulekile kubafundi nakubacwaningi. Lesi sihloko sizoxoxa ngemibuzo eminingana eyisibonelo mayelana... Funda kabanzi

Izixazululo nama-Colloids: Izibonelo Nezingxoxo Izixazululo nama-colloids yizihloko ezimbili ezibalulekile kukhemistri ezibaluleke kakhulu ezicini eziningi zokuphila kwansuku zonke kanye nezicelo ezahlukahlukene zezimboni nezesayensi. Ikhono lokuqonda nokuhlaziya izixazululo nama-colloids liyikhono elibalulekile elidingekayo emikhakheni eminingi yokufunda. Kulesi sihloko, sizoxoxa ngezibonelo ezahlukahlukene… Funda kabanzi

Ama-Biopolymers Ezinto Ezingangcolisi Imvelo: Ikusasa Lezinto Ezingangcolisi Imvelo Isingeniso Enkathini yanamuhla yokwandisa ulwazi ngemvelo, ukusetshenziswa kwezinto ezingcolisi imvelo sekuyinto ebaluleke kakhulu emikhakheni eyahlukahlukene, kusukela ekukhiqizeni kwezimboni kuya emikhiqizweni yansuku zonke yabathengi. Isixazululo esisodwa esidonsele ukunaka ama-biopolymers ezinto ezingaphili. Ama-biopolymers ezinto ezingaphili anikeza okunye okukhangayo esikhundleni sepulasitiki evamile… Funda kabanzi
