Problem 89P

Complete the table. Assume that all concentrations are equilibrium concentrations in moles per liter, M.

Compound

[Cation]

[Anion]

Ksp

SrCO3

2.4 × 10−5

2.4 × 10−5

_____

SrF2

1.0 × 10−3

_____

4.0 × 10−9

Ag2CO3

_____

1.3 × 10−4

8.8 × 10−12

Step-by-Step Solution:
Step 1 of 3

Solution: Here, we are going to complete the given table.

Step1:

Solubility product of any substance is the product of the concentrations of the dissolved ions raised to the power of their stoichiometric coefficients.

Consider the ionization of a substance AB,

                                AB  A+ + B-

Then, the solubility product, Ksp = [A+][B-]

\Step2:

Compound

[Cation]

[Anion]

Ksp

SrCO3

2.4 x 10-5

2.4 x 10-5

5.76 x 10-10

SrF2

1.0 x 10-3

2.0 x 10-3

4.0 x 10-9

Ag2CO3

2.6 x 10-4

1.3 x 10-4

8.8 x 10-12

The ionization of SrCO3 takes place in the following manner:

                                SrCO3  Sr2+ + CO32-

Solubility product for the reaction, Ksp = [Sr2+][CO32-]

                                          = (2.4 x 10-5)(2.4 x 10-5)

                                          = 5.76 x 10-10

    b)        The ionization of SrF2 takes place in the following manner:

                                SrF2
