Redox Reaction
REDOX REACTION: Reduction and oxidation reactions together
One element undergoes reduction, while the other element undergoes oxidation.
Two half reactions are happening: Reduction and oxidation
Electrons are transferred from the element that loses electrons to the element that gains electrons.
To find out if something underwent a redox reaction:
Assign oxidation numbers (if they aren’t given).
• If some oxidation numbers went up and others went down,
Redox: Reduction and
oxidation
that means there was a redox reaction (single replacement reaction).
• If the oxidation numbers only went up or down, there wasn’t a redox reaction.
