Ch. 11: Oxidation-Reduction Reactions Flashcards
1
Q
What property of transition metal changes when they are reduced or oxidized?
A
Their absorption and emission of light is altered such that different frequencies are absorbed – color change!
2
Q
What are spectator ions?
A
Ion that is chemically inert during the reaction. It does not take part/remains unchanged.
3
Q
What does the net ionic equation consist of?
A
All aqueous compounds should be split into their constituent ions.
Solid salts are kept together.
Spectator ions are not included.
4
Q
What is a disproportionation reaction?
A
A specific type of redox reaction in which an element undergoes BOTH oxidation and reduction in producing its products.
2 H2O2 -> 2 H2O + O2
The oxidation number of O in H2O is -2 while the oxidation number of O in O2 is 0.
