The ICE table for the dissociation of Pb(OH)2 is:
The Ksp expression for Pb(OH)2 is:
Plugging in the value for Ksp (1.2 × 10–15) and equilibrium concentrations:
Since the value of Ksp is very small, we can remove +x from the equation to simplify it:
Solving for x:
How many grams of Pb(OH)2 will dissolve in 500 mL of a 0.050-M PbCl2 solution (Ksp = 1.2 × 10–15)?
