The solubility product constant of BaF_2 is 1.7 times 106-6. 3.0 times 10^-3 1.5 times 10^-2

Explanation / Answer

5)

NaI makes [I-] = 0.20 M

for AgI:

AgI       <—>   Ag+      +   I-

s 0.20+s

Ksp = [Ag+][I-]

1.5*10^-16 = s*(0.20+s)

since Ksp is small, s will be small and can be ignored as compared to 0.20

Above expression thus becomes,

1.5*10^-16 = s*(0.20)

s = 7.5*10^-16 M

Answer: 7.5*10^-16 M
