Homework Help: chemistry

Posted by Ashlee on Monday, October 29, 2012 at 8:35pm.

Given a saturated solution of CaF2, write the ionic equilibrium and use it to calculate the solubility of CaF2.

My answers for the ionic equation and ksp values are
CaF2(s)<->Ca2+(aq)+ 2F-(aq)
Ksp= [Ca2+][F-]2
ksp=2.02*10^-4

it asks what will happen to the value of ksp when a solid NaF is added to the solution?

and what would be the new solubility of CaF2 (in a 0.100 mol/L NaF)
