A r edox titration is a titration of a reducing agent by an oxidizing agent or titration of an oxidizing agent by a reducing agent. Typically, this type of titration involves a redox indicator or a potentiometer.Example: Cu 2 + ( aq) + Zn ( s) → Cu ( s) + Zn 2 + ( aq) In this, Cu 2 + gains two electron to form Cu, thus undergoes reduction. While, Zn loses two electrons to give its ions, Zn 2 +. Thus, oxidation takes place. Since, both oxidation and reduction are taking place simultaneously, it is a redox reaction.

When chemical reaction, especially, redox reaction takes place, we do not see the electrons as they appear and disappear during the course of the reaction. What we see is the reactants (starting material) and end products. Due to this, electrons appearing on both sides of the equation are canceled. After canceling, the equation is re-written asSolution. a) Since the half-equation at the left electrode is taken by convention to be oxidation, we have. Ag → Ag+ +e– Ag → Ag + + e –. At the right-hand electrode, then, we must have a reduction: 2H+ + 2e– → H2 2 H + + 2 e – → H 2. Multiplying the first half-equation by 2 and summing gives the cell reaction.

To balance a redox equation using the half-reaction method, the equation is first divided into two half-reactions, one representing oxidation and one representing reduction. The equations for the half-reactions are then balanced for mass and charge and, if necessary, adjusted so that the number of electrons transferred in each equation is the same.Simply put, the photosynthesis reaction we are all familiar with actually consists of TWO redox reactions and a special molecule known as NADP+ and its reduced form, NADPH.
