The solubility product constant is ksp = 2725.47 *
The dissociation reaction of SrF2 is given below:
SrF2 ----------------> + 2
Let us make an ICE table for the reactant and product side:
I 1 0 0
C -s s 2s
E 1 - s s 2s
where,
I denote initial.
C denotes change.
E denotes equilibrium.
ksp is called the solubility product constant.
It is the equilibrium constant for the dissolution of solid substances into an aqueous solution.
A solubility product is the product of the concentration of ions that are present in a saturated solution of an ionic compound.
The ksp can be calculated as follows:
ksp = [ ] * [2
]^2
= (s) * (2s)^2
where s is the solubility.
m = 0.011 g
n = 0.011 / 125.62
where n is the number of moles.
molar mass of SrF2 = 125.62 g / mol
n = 8.8 *
This is for one mole.
For 2 moles it will be
2s = 17.6 * / 0.1 mol / L
= 17.6 * mol / L
100 ml = 100 * = 0.1 L
Therefore,
s = 8.8 * / 0.1
= 8.8 * mol / L
ksp = (8.8 * ) * (17.6 *
)^2
ksp = 2725.47 *
The solubility product constant is ksp = 2725.47 *
