Kev txo qis yog qhov nce ntawm electrons thiab qhov nce ntawm qhov tsis zoo. Nonmetals yog feem ntau oxidized thiab ua cations thaum hlau yog ib txwm txo thiab ua anions.
Ib yam li ntawd, koj yuav qhia li cas yog tias cov hlau yog oxidized lossis txo?
Txheeb xyuas cov ntsiab lus Oxidized thiab txo qis
- Muab cov lej oxidation rau tag nrho cov atoms hauv qhov sib npaug.
- Sib piv cov lej oxidation los ntawm sab reactant mus rau sab khoom ntawm qhov sib npaug.
- Lub caij oxidized yog qhov uas nws oxidation naj npawb nce.
- Lub ntsiab txo yog qhov uas nws tus lej oxidation txo.
Ib tug kuj yuav nug, yog calcium oxidized los yog txo? Redox Reactions
| Kev tshwm sim | Tus neeg sawv cev txo qis | Oxidizing Agent |
|---|---|---|
| Ca + 2 H2O Ca2+ + 2 AW- + H2 | Ca | H2O |
| 2 Al + 3 Nr2 Al2Br6 | Al | Br2 |
| Mg + 2 H+ Mg2++ H2 | Mg | H+ |
| Mg + H2MgO + H2 | Mg | H2O |
Hais txog qhov no, yuav ua li cas thaum lub hlau raug txo?
Oxidation yog thaum lub atom poob electrons, thiab txo yog thaum lub atom nce electrons. Tag nrho cov ionic tebchaw muaj oppositely them ions uas nws cov nqi tshem tawm. Cov hlau oxides yog hlau ions txuas nrog oxygen. Tej yam tshwm sim yuav txo tus hlau los ntawm nws lub xeev them nyob rau hauv lub compound mus rau nruab nrab raws li lub ntsiab.
Qhov twg yog oxidized thiab qhov twg yog txo?
Oxidation thiab Kev txo qis Cov tshuaj tiv thaiv tshwm sim thaum electrons raug xa mus. Lub molecule uas yog oxidized poob ib qho electron thiab cov molecule uas yog txo tau txais cov electron uas poob los ntawm qhov oxidized molecule.
