IB Chemistry: Basics of Redox

This video covers the basics of redox reactions including the different definitions of redox, how to assign oxidation states and how to balance redox equations.

The answers to the redox balancing practice questions:
1) 2MnO4(-) + 16H(+) + 10I(-) → 2Mn(2+) + 8H2O + 5I2

2) 3OCl(-) + 2Fe(OH)3 → 3Cl(-) + H2O + 4H(+) + 2FeO4(2-)

3) 6H(+) + VO4(3-) + Fe(2+) → Fe(3+) + VO(2+) +3H2O
