In a redox reaction Balaning is a bit difficult but it can be done in two steps
1. Identify oxidation states of an element in a chemical formula
2. Balance half reaction equations .
In acid solutionw H+ and H2O to balance
In base solutions OH- and H2O to balance the charge and other atoms
As in this the electron loss or gain is easy to see in the reaction as ion are formed and these reactions are having ploar bond so they form a strong bond
