- The solubility of PbSO4(s) increase with the addition of H2SO4. Why?
- Relevant Equations
- .
I don't quite understand this. When solving PbSO4(s) we get the equilibrium equation:
PbSO4(s) <--> Pb2+ + SO42-.
I know H2SO4 is a strong acid, that will dissociate completely (or almost completely), Like this:
H2SO4 -> H+ + HSO4-
HSO4- -> H+ + SO42-So as far as I can see, the concentration of SO42- increases, which should give a lower solubility of PbSO4(s) (Common ion effect). What am I missing?
