Calculate the solubility product of Ca(OH)2\text{Ca(OH)}_2 if solubility of it is 3moldm−3\sqrt{3} mol \text{dm}^{-3} at 25^{}^{\circ}\text{C}.

Options

  1. A33
  2. B333\sqrt{3}
  3. C2727
  4. D12312\sqrt{3}

Correct answer

D. 12312\sqrt{3}

Step-by-step solution

The dissociation of Ca(OH)2\text{Ca(OH)}_2 is given by:

Ca(OH)2⇌Ca2++2OH−\text{Ca(OH)}_2 \rightleftharpoons \text{Ca}^{2+} + 2\text{OH}^-

Let the solubility of Ca(OH)2\text{Ca(OH)}_2 be ss.

[Ca2+]=s[\text{Ca}^{2+}] = s

[OH−]=2s[\text{OH}^-] = 2s

The solubility product KspK_{sp} is:

Ksp=[Ca2+][OH−]2K_{sp} = [\text{Ca}^{2+}][\text{OH}^-]^2

Ksp=(s)(2s)2=4s3K_{sp} = (s)(2s)^2 = 4s^3

Given s=3 mol dm−3s = \sqrt{3} \text{ mol dm}^{-3}, substituting the value:

Ksp=4(3)3K_{sp} = 4(\sqrt{3})^3

Ksp=4×33=123K_{sp} = 4 \times 3\sqrt{3} = 12\sqrt{3}

Answer: 12312\sqrt{3}
