Oxidation - Kev txo qis Cov tshuaj tiv thaiv. Ib oxidation - txo ( redox) cov tshuaj tiv thaiv yog ib hom tshuaj tiv thaiv uas muaj kev hloov ntawm electrons ntawm ob hom. Ib oxidation - txo cov tshuaj tiv thaiv yog ib qho tshuaj tiv thaiv uas cov oxidation Tus naj npawb ntawm cov molecule, atom, lossis ion hloov pauv los ntawm kev nce lossis poob ib qho hluav taws xob.
Kuj nug, dab tsi yog txhais los ntawm oxidation thiab txo?
Oxidation yog qhov poob ntawm electrons thaum lub sij hawm cov tshuaj tiv thaiv los ntawm ib tug molecule, atom los yog ion. Cov txheej txheem rov qab hu ua txo , uas tshwm sim thaum muaj ib tug nce ntawm electrons los yog lub oxidation Lub xeev ntawm atom, molecule, lossis ion txo.
Tsis tas li ntawd, koj ua li cas oxidation? Kev piav qhia:
- Tus naj npawb oxidation ntawm cov khoom dawb yog ib txwm 0.
- Tus lej oxidation ntawm monatomic ion sib npaug ntawm tus nqi ntawm ion.
- Tus naj npawb oxidation ntawm H yog +1, tab sis nws yog -1 nyob rau hauv thaum ua ke nrog tsawg electronegative ntsiab.
- Tus lej oxidation ntawm O hauv cov tebchaw feem ntau yog -2, tab sis nws yog -1 hauv peroxides.
Dhau li ntawm no, dab tsi yog qhov piv txwv ntawm oxidation txo cov tshuaj tiv thaiv?
Lwm tus piv txwv ntawm redox tshuaj tiv thaiv yog tsim los ntawm hydrogen fluoride. Peb tuaj yeem rhuav tshem tshuaj tiv thaiv down mus soj ntsuam cov oxidation thiab txo ntawm reactants. Hydrogen yog oxidized thiab poob ob lub electrons, yog li txhua hydrogen ua zoo. Ob lub electrons tau txais los ntawm fluorine, uas yog txo.
Dab tsi yog lwm lo lus rau oxidation?
