Cov Lus Nug Piv Txwv Sib Tham Txog Kev Oxidation thiab Kev Txo Kev Taw Qhia Kev Oxidation thiab kev txo qis yog cov ntsiab lus tseem ceeb hauv chemistry uas sib txuas lus thiab tsis sib cais. Cov txheej txheem no tshwm sim tib lub sijhawm hauv kev tshuaj tiv thaiv hu ua kev tshuaj tiv thaiv redox (kev tshuaj tiv thaiv oxidation-reduction). Hauv qhov kev tshuaj tiv thaiv no, cov tshuaj uas tab tom oxidation tso tawm cov electrons, thaum cov tshuaj uas tab tom txo qis… Nyeem ntxiv

Piv txwv ntawm Redox Reactions Cov Lus Nug thiab Kev Sib Tham Txog Redox Reactions Ib qho redox (kev txo qis-oxidation) reaction yog ib qho tshuaj reaction uas cov electrons raug hloov pauv ntawm ob hom tshuaj. Qhov reaction no cuam tshuam nrog kev hloov pauv ntawm tus lej oxidation ntawm cov atoms hauv ib lub molecule, ion, lossis compound. Lo lus "redox" los ntawm ob lub tswv yim: kev txo qis thiab oxidation. Kev txo qis yog cov txheej txheem uas ib yam khoom... Nyeem ntxiv

Piv txwv cov lus nug tham txog Cov Electrolytes Muaj Zog, Cov Electrolytes Tsis Muaj Zog, thiab Cov Tsis Yog-electrolytes. Electrolytes yog lub tswv yim tseem ceeb hauv chemistry uas tseem ceeb heev, tshwj xeeb tshaj yog hauv kev kawm txog cov tshuaj tiv thaiv. Electrolytes yog cov tshuaj uas, thaum yaj hauv dej, tsim cov ions uas ua rau cov tshuaj muaj hluav taws xob. Raws li lawv lub peev xwm los dissociate rau hauv ions, electrolytes raug muab faib ua peb pawg ... Nyeem ntxiv

Cov Lus Nug Piv Txwv Txog Kev Sib Tham Txog Electrolyte Electrolytes yog cov tshuaj uas tuaj yeem ua hluav taws xob thaum yaj rau hauv dej lossis lwm cov kuab tshuaj. Electrolytes raug muab faib ua ob hom tseem ceeb: electrolytes muaj zog thiab electrolytes tsis muaj zog. Cov electrolytes muaj zog raug ionized tag nrho hauv cov kua, thaum cov electrolytes tsis muaj zog tsuas yog ib feem ionized xwb. Electrolytes ua lub luag haujlwm tseem ceeb hauv ntau yam tshuaj lom neeg thiab lub neej txhua hnub. Hauv tsab xov xwm no… Nyeem ntxiv

Cov Lus Nug Sib Tham Txog Electrochemistry: Electrochemistry yog ib ceg ntawm chemistry uas kawm txog kev sib raug zoo ntawm cov tshuaj lom neeg thiab kev hloov pauv zog hluav taws xob. Hauv electrochemistry, muaj ob lub tswv yim tseem ceeb: oxidation (kev tso tawm ntawm cov electrons) thiab kev txo qis (qhov nce ntawm cov electrons). Cov txheej txheem no tuaj yeem pom hauv ob hom electrochemical cells: voltaic cells (galvanic cells) thiab electrolytic cells. Nov yog qee cov lus nug piv txwv nrog rau... Nyeem ntxiv
