Answer to Problem 6STP

B is the correct option.

Explanation of Solution

  CaF2 dissociates in aqueous solution as follows,

  CaF2(s)Ca2+(aq)+2F(aq)                    s                2sWhere s= solubility of CaF2.  

Expression for Ksp

  [Ca2+][F]2 …...(1)

Putting the solubility values in equation (1) we get,

   K sp =s× (2s) 2 =4 s 3 =4× (2.15× 10 4 ) 3 =4×(9.93× 10 12 ) =3.98× 10 11

Conclusion

Therefore, B is the correct option.
