ink this is happening in acidic solution, the
xtbook doesn't specify anything more. Can you
lease help me understand if | got the half
actions correct?
KMnOy4 + FeSO4 + Hy SO4 — K5SOy
+ MnSO, + Fe, SOy 3 + H,
found out that manganese is reduced as the xidation number goes from +7 to +2 and iron ets oxidized as the oxidation number goes from
-2 to +3. | wrote the two half reactions,
for
1e reduction and
for the oxidation. Did I get
hem right?
KMnOy, + H,SO,4 — KySOy + MnSO
FeSO, — Fe, SOy 3
started working on the reduction half-equation nd this is what | came up with after balancing
toms and charge:
10e” + 10H" + 2KMnO4 + 3H5S04
— K,S0, + 2MnSOy + 8 Hy
low comes the trouble. How do | balance iron and fur in the avidation half-reaction (R)2
