Probably. There is a large difference in electronegativity so they will probably ionize.

CaF2 (the mineral fluorite) is only sparingly soluble in water. It's solubility product is approximately 1.46 * 10^-10 at 25 C. An aqueous solution in equilibrium with pure solid CaF2 at this temperature would have a Ca++ concentration of ~3.32 * 10^-4 M, and a F- concentration twice this value (~6.63 * 10^-4 M).

Sorry but CaF2 is found in nature as the mineral Fluorite which is not water soluble.

Calcium ionic compounds tend to be solids in water, due to the ionic compound's relative stabilities. Flouride has a VERY high affinity for calcium and bonds with it. I believe it is not soluble in water. I also believe it is the compound that is formed on the outside layer of your teeth when you drink flourinated water.
I could be wrong...good question

Because they have been putting calcium floride in city water for years and we know its water soluble...I'm sure there is a scientific explination but thats way more boring than just putting the crap in water and seeing if it disolves.

I would expect it to dissolve in water because I looked up the solubility constant which led me to believe it would dissolve.

It's composed of two highly polar ions. Water loves to dissolve polar materials.

F is extremely electronegative. It will be attracted more to the H2O than to the Ca.

it's a salt with easily polarizable ions
