Homework Help: chemistry

Posted by John on Sunday, October 21, 2012 at 10:07pm.

Will a fluoride concentration of 1.0 mg/L be soluble in a water containing 200 mg/L of calcium?

This is what i found for ksp
CaF2<--> Ca(2+) +2F(-) Ksp=(x)(4x^2) where x=solubility Therefore, Ksp=3.7 x 10^-11

and for Qsp I am not sure how to go on about calculating that.
