Actually this depends on what kind of titration is being done. If we are titrating Ba (OH) 2 using an acid, it actually does not matter that some Pb (OH) 2 is formed because the acid will still neutralize even those OH - ions that combined with lead Pb.

But other than that, generally we can say that the calculated concentration can be affected because lead (II) chloride would co-precipitate with Ba (OH) 2 to form Pb (OH) 2
