ionic solid SrF2. When dissolved in pure water, its solubility is found to be 8.9×10-4 M.

Give the formula of the anion in this compound.

What is the concentration of this anion in a saturated solution of SrF2?

Determine the value of Ksp for SrF2.

Please note that the chemical reaction is:

SrF2 --> Sr^2+  + F^-

so we have:

[Sr^2+] = 8.9*10^(-4)

[F^-] = 2 *8.9*10^(-4) = 17.8*10^(-4)

and:

Ksp = 2.819 * 10^(-9)
