Introduction to Oxidation, Reduction, and Half Equations

The video covers oxidation, reduction, and half equations. The speaker explains the concepts of oxidation and reduction, and how they relate to gaining or losing electrons. They also discuss balancing half equations and identifying whether a species is oxidized or reduced based on the changes in electrons. The speaker gives examples of reactions at the cathode (cat ions gaining electrons) and anode (anions losing electrons), and how to balance the charges in each reaction using electrons.
