Solution: Ksp for CaF2 is 3.9 × 10−11. Would a precipitate of CaF2 form if Ca(NO3)2 and NaF solutions were mixed such that [Ca2+] = 2.0 × 10−4 M, and [F−] = 3.0 × 10−4 M? 1. no  2. yes, because Q is smaller t

Problem

Ksp for CaF2 is 3.9 × 10−11. Would a precipitate of CaF2 form if Ca(NO3)2 and NaF solutions were mixed such that [Ca2+] = 2.0 × 10−4 M, and [F] = 3.0 × 10−4 M?

1. no 

2. yes, because Q is smaller than Ksp

3. yes, because Q is larger than Ksp
