  1. Redox > Redox – Oxidation: loss of electrons Transfer Reduction: gain of electrons of electrons • Assign oxidation #s to every atom in the equation • Orange book pg. 591 2KBr + Cl2 2KCl + Br2

  2. The reactant whose oxidation # goes up is oxidized (lost e-s) • The reactant whose oxidation # goes down is reduced (gained e-) The oxidizing agent = the substance reduced Thereducing agent = the substance oxidized

  3. Balancing redox reactions **Must balance the atoms AND the charges** • Have to know whether the reaction takes place in an acidic or basic solution • Balance the ½ reactions then add together for the overall reaction Balance the following redox reactions: 1. Cr2O7-2 + I- Cr+3 + I2 (in acidic solution) 2. N2O + ClO- NO2- + Cl- (in basic solution)
