Question

The Ksp for BaF2 is 2.4 x 10-5. When 10 mL of 0.01 M NaF is mixed with 10 mL of 0.01 M Ba(NO3)2, will a precipitate form?

A. Yes, because Q is 1 x 10-12 and since it is less than Ksp a precipitate will form.

B. No, because Q is 1.25 x 10-7 and since it is less than Ksp no precipitate will form.

C. No, because Q is 1 x 10-12 and since it is less than Ksp no precipitate will form.

D. Yes, because Q is 2.5 x 10-5 and since it is greater than Ksp a precipitate will form.

E. Yes, because Q is 1.25 x 10-7 and since it is less than Ksp a precipitate will form.

B. No, because Q is 1.25 x 10-7 and since it is less than Ksp no precipitate will form.
