A solution contains 0.10M iodide ion, I-, and 0.10Mcarbonate ion, CO32-. If solidPb(NO3)2 is slowly added to the solution,which salt will precipitate first, PbI2 orPbCO3? What will the concentration of the first ion that precipitates (I- or CO32-) be when the second, more soluble, salt begins to precipitate?
