Redox
Chemistry Unit 4
Term | Definition |
---|---|
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. |
