With most compounds, on descending the group, the hydration energy decreases more rapidly than the lattice energy: hence the compounds become less soluble as the metal gets larger. However, with fluorides and hydroxides the lattice energy decreases more rapidly than the hydration energy, and so their solubility increases on descending the group. The solubility would then equal the concentration of either the Ag or Cl ions.solubility = [Ag+] = [Cl-]1.26 x 10-5 M = [Ag+] = [Cl-]Ksp = [Ag+][Cl-]Ksp = (1.26 x 10-5)(1.26 x 10-5)Ksp = 1.6 x 10-10, The dissociation reaction of BaF2 in water isBaF2 (s) Ba+ (aq) + 2 F- (aq)This reaction shows that for every mole of BaF2 that dissolves, 1 mole of Ba+ and 2 moles of F- are formed.
