14.5 Part a

If we are combining redox reductions and it has to be in basic solution, does the final answer have to include (OH-)?
I am asking this because the solutions manual for 14.5 part a does not have (OH-) in its final answer

The reason that OH- is not included is because they cancel out when you balance the redox reaction.

If there are any H+ ions, you need to convert them to H2O using OH-.

Redox reactions in basic solutions don't need to have OH- in the final balanced equation if they cancel out. OH- would only show up in the final equation when the two sides of the equation don't require the same amount of OH- when balancing.

No, you don't have to. It may be canceled out or doesn't never needed to balance the equation.
