Final answer:
To balance a redox equation, the oxidation half-reaction is multiplied by 3 and the reduction half-reaction by 2 to ensure the same number of electrons are transferred in both reactions.
Step-by-step explanation:
In redox reactions, it is imperative to balance the number of electrons lost in the oxidation half-reaction with the number of electrons gained in the reduction half-reaction.
Based on the information provided, in order to balance the equation, the oxidation half-reaction must be multiplied by 3 and the reduction half-reaction must be multiplied by
2. This ensures that the same number of electrons is involved in both processes, thereby maintaining electrical neutrality.
Multiplying by these specific numbers allows for the charges and atoms to be balanced correctly on both sides of the overall chemical equation.
In order to balance the number of electrons lost and gained, the oxidation half-reaction must be multiplied by 2 and the reduction half-reaction must be multiplied by
3. This ensures that the electrons lost in the oxidation half-reaction are equal to the electrons gained in the reduction half-reaction.
By multiplying the oxidation and reduction half-reactions by the appropriate coefficients, the overall chemical equation can be balanced.
