The third reaction:
2H2SO4(aq) + 2Ba(OH)2(aq) → 2BaSO4(s) + 4H2O(l)
is not an oxidation–reduction reaction. All oxidation numbers remain the same (H +1, S +6, O −2, Ba +2), so no species is oxidized or reduced. It's an acid–base / precipitation reaction.
2H2SO4(aq) + 2Ba(OH)2(aq) → 2BaSO4(s) + 4H2O(l)
