From each of the following ion concentrations in a solution, predict whether a precipitate will form in the solution. Hint -- First write the balanced solubility equation so you know how many of each ion results from the disassociation. Then calculate Q꜀ and compare to Kₛₚ to predict if it will precipitate.
a. [Ba²⁺] = 0.020 M, [F⁻] = 0.015 M (Kₛₚ of BaF₂ is 1.0 x 10⁻⁶)
b. [Pb²⁺] = 0.035 M, [Cl⁻] = 0.15 M (Kₛₚ of PbCl₂ is 1.6 x 10⁻⁵)
