Question

How are half-reaction useful?

Answer 1

We can use the half-reaction method to balance the equations of redox reactions occurring in aqueous solution. ... Each half-reaction is balanced for mass and charge, and then the two equations are recombined with appropriate coefficients so that the electrons cancel.

Step-by-step explanation:

Answer 2

Half-reactions are often used as a method of balancing redox reactions. For oxidation-reduction reactions in acidic conditions, after balancing the atoms and oxidation numbers, one will need to add H + ions to balance the hydrogen ions in the half reaction.
