IB Chemistry 3.1.6 Oxidation states Questions
Practise assigning oxidation states in ions, acids and coordination species, and stating redox changes in the exact form IB mark schemes accept.
How this is tested
- calculate oxidation states in species such as HNO2, NO2− and Na2CrO4
- identify which formulae contain an atom in the +3 oxidation state, for example FeCl3 and BrF3
- state initial and final oxidation states in a redox change, e.g. nitrogen +2 to 0, using +3 or III rather than 3+
