The solubility product constant is ksp = 2725.47 * 10^{-12}

The dissociation reaction of SrF2 is given below:

SrF2 ----------------> Sr ^{2+} + 2F^{-}

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 = [ Sr ^{2+}] * [2F^{-}]^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 * 10^{-5}

This is for one mole.

For 2 moles it will be

2s = 17.6 * 10^{-5} / 0.1 mol / L

  = 17.6 * 10^{-4} mol / L

100 ml = 100 * 10^{-3} = 0.1 L

Therefore,

s = 8.8 * 10^{-5} / 0.1

  = 8.8 * 10^{-4} mol / L

ksp = (8.8 * 10^{-4} ) * (17.6 * 10^{-4} )^2

ksp = 2725.47 * 10^{-12}

The solubility product constant is ksp = 2725.47 * 10^{-12}

How many moles of Fe2O3 are in 203 g of the compound?
ruslelena [56]
The equation is :
moles=mass/molar mass
so, the mass is 203 and molar mass is 159.69 
You divide the 203 by 156.69 as the equation shows
so the moles is 1.27 mol.

Which of the following atoms will not react with water​
Sati [7]

Answer:

Among Na ,K , Pb , Li , The atom which does not react with water is :

<u>Pb</u>

Explanation:

Li  : Reacts slowly with water

Na ,K  : Reacts vigorously with water

Pb : It does not reacts with water because :- Pb oxidize in presence of  atmospheric oxygen to form lead oxide (PbO) . this PbO form a layer over the surface of Pb and make it inert to water.
