Question

Solid lead nitrate is added to a solution that is 0.020 M in [OH-] and [SO4-2]. Addition of the lead nitrate does not change the volume of the solution. (a) SHOW BY CALCULATION which compound, PbSO4 or Pb(OH)2 will precipitate first. (Ksp PbSO4 = 1.8 x 10-8, Ksp Pb(OH)2 = 2.8 x 10-16) (b) Calculate the pH of the solution when the PbSO4 first starts to precipitate.

Step 1

First, we need to find the concentrations of Pb2+ required to precipitate each compound. We can do this by using the Ksp values and the given concentrations of OH- and SO4-2. For PbSO4: Ksp = [Pb2+][SO4-2] 1.8 x 10^-8 = [Pb2+](0.020) [Pb2+] = (1.8 x 10^-8) / Show more…
