The benefits of adding small amounts of fluoride to your water are shown to be good for many (but not all)
people. Consequently, many municipalities fluoridate their water. The source of the fluoride is CaF2 . The Ksp of
CaF2 is easy to find in a reference book or the web, but for the sake of expediency here it is: Ksp = 3x10-11 . Given
just that little bit of information and what you know about the way solids like CaF2 dissociate in water, how many
moles of F2 would expect to dissolve for every one (1) mole of CaF2 you add to the water? (15 points)
