Answer:The solubility product expression for
.

K_(sp)=[Ca^(2+)]* [F^-]^2

Step-by-step explanation:

Solubility product is defined as product of concentration of dissociated ions raised to the power equal to respective stoichiometric coefficient.

The solubility product of
CaF_2

$CaF_2\rightleftharpoons Ca^(2+)+2F^-$

K_(sp)=[Ca^(2+)]* [F^-]^2

The solubility product expression for
.

K_(sp)=[Ca^(2+)]* [F^-]^2
