Homework 6th edition, 14.5, part d

Postby Bianca Barcelo 4I » Wed Feb 27, 2019 12:52 am

I am getting confused with when species can act both as oxidizing and reducing agents. What are the general guidelines when dealing with species acting as both in basic solutions?

For those kinds of problems, start by writing out each of the half reactions, even if one element is duplicated by appearing in both half reactions. Then, balance as usual and add the two half reactions together once the electrons can cancel. At the end, make sure to neutralize any excess H+ you may have with OH- on both the reactants and products sides. Make sure to fully cancel everything out and balance before giving your final answer.
