Determine the minimum concentration of the precipitating agent on the right to cause precipitation of the cation from the solution on the left. 3.0*10^-2 M BaNO3;NaF
Answered by DrBob222
BaF2 ==> Ba^+ + 2F^-

Ksp = (Ba^+2)(F^-)^2

The problem tells you (Ba^+2) = 0.030M
Substitute into Ksp and solve for (F^-)
