babunello [35]

Answer: 1.70\times 10^{-6}

Explanation:

Solubility product is defined as the equilibrium constant in which a solid ionic compound is dissolved to produce its ions in solution. It is represented as

The equation for the ionization of the BaF_2 is given as:

BaF_2\rightarrow Ba^{2+}+2F^-

When the solubility of BaF_2 is S moles/liter, then the solubility of Ba^{2+}  will be S moles/liter and solubility of F^- will be 2S moles/liter.

By stoichiometry of the reaction:

1 mole of BaF_2 gives 1 mole of Ba^{2+ and 2 moles of F^-

K_{sp}=[Ba^{2+}][F^{-}]^2

K_{sp}=s\times (2s)^2

K_{sp}=4\times (7.52\times 10^{-3})^3

K_{sp}=1.70\times 10^{-6}

Thus K_{sp} for BaF_2 is 1.70\times 10^{-6}
