+ Oxygen
+ Oxidation State - 2Reduction- Oxygen
- Oxidation State
+ Electrons
+ Hydrogen - 3Na + Cl -> Na+ + Cl-Na (Oxidation)
Cl (Reduction) - 4Fe2O3 + 3CO -> 2Fe + 3CO2Fe (Reduction)
CO (Oxidation) - 5Zn + 2H+ -> Zn2+ + H2Zn (Oxidation)
H (Reduction) - 6What is an Anode?It is oxidised
Mg -> Mg2+ - 7What is a Cathode?It is reduced
Mg2+ -> Mg - 8Oxidation Number Rules1. Will be 0 in it's natural state (e.g. Al or Al2)
2. Same as charge (e.g. Sn2+ will be +2)
3. The sum of all oxidation numbers in a neutral atom is 0
4. Oxygen is usually -2
5. Hydrogen is usually +1
6. F, Cl, Br usually -1 unless w/oxygen - 9Oxidation Numbers on Periodic Table
- 10Half Reactions from Cl2 + Fe2+ -> 2Cl- + Fe3+Cl2 + 2e- -> 2Cl-
