A saturated solution of MgF2 has [Mg2+] = 2.6 × l(T4Mand[F−] = 5.2 × 10−4M. What is the value of Ksp for MgF2?

Solution 81P :

Step 1:

Given :

[Mg2+] = 2.6 × l0-4 M

[F-] = 5.2 × 10-4 M

Ksp for MgF2 = ?

Ksp is the solubility product constant. It is the equilibrium constant of a solid substance that is dissolved in aqueous solution. It represents the level at which a solute dissolves in solution. It changes with the temperature. Ksp is the mathematical product of the concentrations of the ion dissolved raised to the power of their stoichiometric coefficients.

For the reaction :

aA(s) ⇋ cC(aq) + dD(aq)

The formula of Ksp is :

Ksp =
