Chapter 16, Problem 16.124SP

Interpretation Introduction

Interpretation:

Whether $\text{Mg}{\left(\text{OH}\right)}_{\text{2}}$ will be precipitated or not from a solution containing $$

$\left[{\text{Mg}}^{\text{2+}}\right]\text{=2}\text{.5}\times {\text{10}}^{\text{-4}}\text{ M}$ and $\text{pH=10}\text{.80}$.

Concept introduction:

• For precipitation of a salt the ionic product of the salt must be greater than the solubility product.

Given:

$\left[{\text{Mg}}^{\text{2+}}\right]\text{=2}\text{.5}\times {\text{10}}^{\text{-4}}\text{ M}$ and pH of the solution as $10.80$
