Recall that oxidation takes place at the anode and reduction takes place at the cathode. When the anode and cathode are connected by a wire, electrons flow from anode to cathode. A typical
Does oxidation take place?
Oxidation takes place as a molecule, atom, or ion raises its oxidation state. The reverse mechanism is known as reduction, which happens as the electron gain or the oxidation state of the atom, molecule, or ion reduces. The above reaction oxidizes hydrogen and reduces fluorine.
How do you know where oxidation occurs?
Oxidation numbers represent the potential charge of an atom in its ionic state. If an atom's oxidation number decreases in a reaction, it is reduced. If an atom's oxidation number increases, it is oxidized.
