We can fix this by putting the coefficient 2 in front of the product. it should be immediately clear that the Cl atoms are not balanced. Balancing simple redox reactions can be a straightforward matter of going back and forth between products and reactants. Use the solvent, or parts of it, as a reactant or a product in balancing a redox reaction. For example, in the redox reaction of Na and Cl 2: Na + Cl 2 → NaCl. A. 0 electrons. B. 6 electrons.
