Barium fluoride is transparent from the ultraviolet to the infrared, from 150–200 nm to 11–11.5 µm. The solubility of a partially soluble salt in water can be written as an equilibrium between its solid form and its solvated ions. Solubility product constant (K sp) (or the solubility product) is the product of the molar concentrations of the constituent ions, each raised to the power of its stoichiometric coefficient in the equilibrium equation.For instance, if a compound A a B b is in equilibrium with its solution A saturated solution of Barium Fluoride, BaF2, was prepared by dissolving solid BaF2 in water. Ksp = [Ba+2][F-1]2 1.0 x 10-6 = (x) (2x)2 = 4x3 solving for x, we get: x = 6.30 x 10-3 M Since "x" represents the molarity of the Ba+2 ion, and we get one mole of barium ions for each mole of barium fluoride that dissolves, we obtain a molar solubility for BaF 2 of 6.30 x 10-3 M.
