Chapter 15, Problem 78E

Interpretation Introduction

Interpretation:

For each of the given compounds, solubility product $\left({\text{K}}_{\text{sp}}\right)$ expression has to be shown along with the equation which shows the solubility of the compound in water.

Concept Introduction:

When an ionic compound dissolved in water it breaks into its constitute ions, water molecule has negative charge on oxygen molecule and positive charge on hydrogen atoms due difference in electronegativity between hydrogen and oxygen atom.

Solubility product have unit of concentration.

Solubility product $\left({\text{K}}_{\text{sp}}\right)$ applies in a situation when a compound does not completely dissolve in the solvent. Solubility product $\left({\text{K}}_{\text{sp}}\right)$ may be defined as product of its dissolved ion concentration raised to the power of their stoichiometric coefficient.

For the given chemical equation $\text{A + B }\to \text{ C +}\text{}\text{D}$, the solubility product is given by ${\text{K}}_{\text{sp}}\text{ = }\left[\text{C}\right]\left[\text{D}\right]$.
