Do you have to balance chemical equations before doing half reactions for redox?

    Balance a redox reaction equation ....

    That's sort-of the point of using the half-reaction: to balance the net ionic equation (or the molecular equation.)

    Each half-reaction must be both mass balanced (number of each kind of atom) and charge balanced. When the two half-reactions are adjusted with an overall coefficient, they can be added together because the number of electrons gained and lost cancel out and you get the balanced net ionic equation.

      The answer is accurate. Don't be put off by the "thumbs down." It's the work of a troll.

    No - you can balance each half reaction if needed
