Chemistry Unit 4

Redox The transfer of electrons
Fixed oxidation states Some elements nearly always have the same oxidation state in their compounds.
Displacement reactions A type of reaction where part of one reactant is replaced by another reactant.
Oxidation The gain of oxygen.
Oxidation state (for number) The loss of electrons.
Oxidation states in compound ions The total oxidation state adds up to the charge.
Oxidising agents accepts electrons from another reactant and is itself reduced.
Reducing agents donates electrons to another reactant and is itself oxidised.
Reduction The loss of oxygen.
Simples ions The charge on ion. Ions in compounds where the other half is not given.
Reduction state (for number) The gain of electrons.
Oxidation state for Reduction Decrease
Oxidation state for Oxidation Increase
Redox reaction A reaction in which oxidation and reduction both take place.
