The molal solubility m, of the sparingly soluble salt BaF2 in water at 25°C, following from the dissolution equilibrium BaF2(s) = Ba?+(aq) + 2 F¯(aq) , is ms = 1.830 x 10-2 mol kg¬1. What is the value of the solubility product equilibrium constant Ksp(BaF2) in water at 25 °C? Assume that the Debye-Hückel limiting law for the activity coefficients applies in this situation.

Question
The molal solubility m, of the sparingly soluble salt BaF2 in water at 25°C, following
from the dissolution equilibrium
BaF2(s) = Ba?+(aq) + 2 F¯(aq),
is m, = 1.830 x 10-2 mol kg-1. What is the value of the solubility product equilibrium
constant Ksp(BaF2) in water at 25°C? Assume that the Debye-Hückel limiting law for
the activity coefficients applies in this situation.
