Why doesn't potassium ion K+ from KMnO4 appear in the following two unbalanced equations: MnO4– + C2O42– Mn2+ + CO2
MnO4– + Fe2+ Mn2+ + Fe3+ ?
A. KMnO4 is not added to either reaction.
B. The presence of K+ would result in a net positive charge in the products.
C. The equations cannot be balanced if the potassium ion K+ is present.
D. K+ is a spectator ion and redox reactions are written as net ionic reactions.
E. None of these.
i think it's D
chemistry(check my asnwer) -
D is correct.
