Ksp problem

How many mL of HCl 0.3M I must add to 5 mL di Pb(NO3)2 0.3M to start the precipitation of PbCl2, knowing that its Ksp is 1.62·10-5?

From Ksp formula

Ksp=[Pb2+]·[Cl-]2
Ksp=[Pb2+]·[Cl-]2

S=Ksp4----v3=1.59·10-2
S=Ksp43=1.59·10-2


S is the concentration of ions in mol/L above which begins the formation of the precipitate. Knowing this, what should I do?
