In the ion-electron method (also called the half-reaction method), the redox equation is separated into two half-equations - one for oxidation and one for reduction. Each of these half-reactions is balanced separately and then combined to give the balanced redox equation.

Half reaction method
The half reaction method is a technique used to balance redox equations by balancing the oxidation and reduction half reactions separately and then combining them to form a balanced overall equation. This method is also known as the ion-electron method or the half-cell method.
Steps involved in the half reaction method:
1. Identify the oxidation and reduction half reactions: Determine the species that are being oxidized and reduced in the given redox equation. The species that loses electrons is oxidized, while the species that gains electrons is reduced. Split the overall equation into two half reactions accordingly.
2. Balance the atoms: Balance the atoms in each half reaction, except for hydrogen and oxygen. Start by balancing the atoms other than hydrogen and oxygen, ensuring that the number of atoms on both sides of the equation is equal.
3. Balance the oxygen atoms: Add water molecules (H2O) to the side of the equation that lacks oxygen atoms. The number of water molecules added should be equal to the number of oxygen atoms needed to balance the equation.
4. Balance the hydrogen atoms: Add hydrogen ions (H+) to the side of the equation that lacks hydrogen atoms. The number of hydrogen ions added should be equal to the number of hydrogen atoms needed to balance the equation.
5. Balance the charge: Add electrons (e-) to one side of the equation to balance the charges on both sides. The number of electrons added should be equal to the difference in charges between the two sides of the equation.
6. Combine the half reactions: Multiply each half reaction by a factor such that the number of electrons in both reactions is equal. This is done to cancel out the electrons when combining the reactions.
7. Cancel out the electrons and combine: Add the two balanced half reactions together, canceling out the electrons on both sides of the equation. The resulting equation is the balanced overall redox equation.
By following these steps, the half reaction method allows for the systematic balancing of redox equations. It ensures that the number of atoms and charges are balanced on both sides of the equation, providing a complete and accurate representation of the chemical reaction.
