Chapter 17.4, Problem 17.4.2SR

Interpretation Introduction

Interpretation:

The precipitate formed from the given solutions has to be predicted.

Concept introduction:

• The solubility product constant ( ${\text{K}}_{\text{sp}}$) is defined as the equilibrium between compound and its ions in an aqueous solution.
• Solubility product is the multiplication of concentration of dissolved ion,  raised to the power of coefficients.
• Ionic compound ${\text{A}}_{\text{3}}\text{B}$ ${\text{K}}_{\text{sp}}\text{=}{\left[\text{A}\right]}^{\text{3}}\left[\text{B}\right]$.
• Reaction quotient (Q) is the ratio of product of concentration of products  to that of  product of concentration of reactants, raised to the power of coefficients.
• ${\text{Q > K}}_{\text{sp}}$ , precipitation will happen
• ${\text{Q is less than K}}_{\text{sp}}$, more solute can dissolve in solution that is no precipitation.
• ${\text{Q is equal to K}}_{\text{sp}}$, no more solute can dissolve or precipitate in solution.
