Determine whether a precipitate of lead chloride, PbCl2(s), will form when a 2.0 × 10−3 mol/L solution of lead nitrate, Pb(NO3)2(aq), is combined with 1.0 × 10−3 mol/L solution of hydrochloric acid, HCl(aq), in equal volumes. a. Write the equilibrium expression for PbCl2(s).
b. Ksp for PbCl2(s) is 1.6 × 10−5. Calculate the trial ion product, Q, for this reaction.
c. Will a precipitate form? Explain.
