Calculate the molar solubility of MgF2 in 0.08M MgCl2 at 25 degrees C.

• Chemistry - DrBob222, Tuesday, February 8, 2011 at 1:07am

MgF2 ==> Mg^+2 + 2F^-

Ksp = (Mg^+2)(F^-)^2
Substitute 0.08 M for (Mg^+2) and solve for (F^-).

do I use the Ksp of MfF2 and plug it in the equation?

• Chemistry - DrBob222, Tuesday, February 8, 2011 at 11:51pm

Yes.

• Chemistry - James, Monday, October 3, 2011 at 9:02pm

from the equation:

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

there are two unknown how do we solve it

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

the value 3.0x10^-5 was wrong for me?
