Determination of Solubility Product Constant (Ksp) of SrF2

Introduction

The solubility product constant (Ksp) is a measure of the solubility of a sparingly soluble salt, such as SrF2. In this article, we will discuss the determination of Ksp of SrF2 and its solubility in 0.1 M NaF solution.

Given Data

The solubility product constant (Ksp) of SrF2 is given as:

Ksp = 1 x 10^(-10)

Additionally, the solubility of SrF2 in 0.1 M NaF is given as:

[SrF2] = 1 x 10^(-a) M

Determination of 'a'

To determine the value of 'a', we can use the expression for Ksp in terms of the solubility of SrF2 in 0.1 M NaF.

Ksp = [SrF2]^2

Substituting the given values, we get:

1 x 10^(-10) = (1 x 10^(-a))^2

Simplifying the equation, we get:

10^(-10) = 10^(-2a)

Equating the exponents, we get:

-10 = -2a

a = 5

Therefore, the value of 'a' is 5.

Conclusion

In this article, we determined the value of 'a' using the given solubility product constant (Ksp) of SrF2 and its solubility in 0.1 M NaF solution. The value of 'a' is found to be 5.
