Question

Which is the solubility product expression for CaF2(s)? 

[Ca2+]/[F–]2 
[Ca2+][F2–] 
[Ca]+[F]2 
[Ca2+][F–]2

Answer 1

Answer:The solubility product expression for
`CaF_2`.

`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
`CaF_2`.

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