Calculate the molar solubility of MgF2 in 0.08M MgCl2 at 25 degrees C.
Answered by DrBob222
MgF2 ==> Mg^+2 + 2F^-

Ksp = (Mg^+2)(F^-)^2
Substitute 0.08 M for (Mg^+2) and solve for (F^-).
Answered by Melissa
do I use the Ksp of MfF2 and plug it in the equation?
Answered by DrBob222
Yes.
Answered by James
from the equation:

Ksp=(.08M)(F^-)^2

there are two unknown how do we solve it

Answered by laurie
you have to find the Ksp in the back of your chemistry book.
