A solution containing sodium fluoride is mixed with one containing calcium nitrate to form a solution that is 0.015 M in NaF and 0.010 M is Ca(NO3)2. Calculate the reaction quotient (Q) for the possible cross product CaF2, and compare Q to the solubility product constant (Ksp) of CaF2 to determine if a precipitate will form. Note, you will have to look up the Ksp for CaF2.
