Half rxn

Postby Jennifer Torres 2L » Wed Feb 27, 2019 11:47 pm

Could someone explain what exactly a half reaction is? both conceptually and mathematically?

Conceptually, a half reaction is either a reduction half reaction or a oxidation half reaction. A half reaction makes up one part of a redox reaction. The redox reaction is separated into two half reactions by identifying identify what is getting reduced and what is getting oxidized. Mathematically, a half reaction is calculating the oxidation number of an atom. The next step is balancing which requires both half reactions. Remember that a half reaction cannot exist on its own, it is a part of a redox reaction which consists of both a reduction half reaction and an oxidation half reaction.
