Homework Statement
Balance the following red-ox reaction that occurs in acidic solution.
Homework Equations
Pb(s) + PbO[tex]_{2}[/tex](s) + H[tex]_{2}[/tex]SO[tex]_{4}[/tex](aq) [tex]\rightarrow[/tex] PbSO[tex]_{4}[/tex](s)
The Attempt at a Solution
I did not see a change of oxo state from the sulfur, oxygen, or hydrogens. The lead is getting oxidized and the lead dioxide is getting reduced. But there is only one product...I tried leaving in the hydrogen sulfate in one of the half reactions, even though its oxo state does not change, and I ended up with an imbalanced equation. Here are the steps that I follow:
1.Seperate into two half reactions.
2.Balance the atoms that undergo a change in oxidation state.
3.Balance other atoms, except O's or H's
4.Balance oxygens by adding H2O
5.Balance hydrogen by adding H[tex]^{+}[/tex]
6.Balance the charge by adding electrons (e-) to both sides until the charge is the same on both sides, starting with the most positive side.
7.equalize the electrons on both sides
8.add the two half reactions, cancel like terms.
Sorry for the somewhat long post. Oh and I'm a first time poster on PF, so I hope I didn't screw up anything too badly.
