Video transcript. - In this video we will be talking about a new type of reaction called "Redox Reaction". And these are very commonly found. Photosynthesis is an example of redox reaction. The chemical reaction that happens within a battery which powers your phone or laptop devices, this is also an example of redox reaction.Balancing redox reactions is slightly more complex than balancing standard reactions, but still follows a relatively simple set of rules. One major difference is the necessity to know the half-reactions of the involved reactants; a half-reaction table is very useful for this.A redox reaction can be defined as a chemical reaction in which electrons are transferred between two reactants participating in it. This transfer of electrons can be identified by observing the changes in the oxidation states of the reacting species.coined for this class of chemical reactions.
