(a) Interpretation: The net ionic equation needs to be determined and balanced in the acidic medium. Concept introduction: The rules to balance redox reactions in basic medium are as follows: Determine the oxidation numbers of the elements and write the oxidation and reduction half equation. Balance the atoms of elements other than H and O atoms. Use H 2 O to balance the number of O atoms, H+ to balance the number of H atoms and the electrons for charge balance. Equalize the number of electrons on both the half reactions and then add the half reactions.

Solution Summary: The author explains how the net ionic equation must be determined and balanced in the acidic medium.
Method Method Redox reactions are generally balanced using two processes. The first method is based on the redox reaction’s division into two reactions where one is involved in oxidation and the other in reduction (half reaction method) and the second one is based on the reducing and oxidizing molecule’s oxidation number variation (oxidation number method).
