L’oxydant capte les électrons ; le réducteur les cède.
📐 Formula - Le modèle d’une demi-équation est , où est le nombre d’électrons captés.
1. How is a redox couple formed and conventionally written?
2. In a reaction, species X gains electrons and becomes its conjugate reduced form; what role does X play?
3. During electron transfer, species Y releases electrons and becomes its conjugate oxidized form; what role does Y play?
What does a redox couple associate?
An oxidant and a reductant derived from the same chemical element.
How is a redox couple written?
Oxidant/reductant.
What does an oxidant do with electrons?
It gains electrons to become its conjugate reductant.
What does a reductant do with electrons?
It gives up electrons to become its conjugate oxidant.
What does an electron half-equation represent for a redox couple?
The transfer of electrons for one oxidizing-reducing couple.
What is the general model for an electron half-equation?
