Balance the following redox reaction and do not include the
states of matter. In acidic solution, manganese(IV) oxide reacts
with sulfite ion to form manganese(II) ion, water, and dithionate
ion (S2O62-).
2. Balance the first redox reaction in acidic solution and the
second redox reaction in basic solution.
S + NO3- → SO2 + NO
Cr2O72- + Fe2+ -----> Cr3+ + Fe3+
3. Balance the following redox reactions that occur in
acidic solution using the half-reaction method.
a. Cr(s) + NO3-(aq) → Cr3+(aq) + NO(g)
b. CH3OH(aq) + Ce4+(aq) → CO2(aq) +
Ce3+(aq)
c. SO32-(aq) + MnO4-(aq) → SO42-(aq) +
Mn2+(aq)
