ON Question 15 (7 points) Determine whether a precipitate of lead chloride, PbCl2(s), will form when a 2.0 x 10-3 mol/L solution of lead nitrate, Pb(NO3)2(aq), is combined with 1.0 x 10-3 mol/L solution of hydrochloric acid, HCl(aq), in equal volumes. (a) Ksp for PbCl2(s) is 1.6 x 10-5. Calculate the trial ion product, Q. for this reaction. (b) Will a precipitate form? 7 A
