Chapter 17.1, Problem 17.1CC

Interpretation Introduction

Interpretation:

From the given lead compounds, the largest amount of lead ion yields while dissolving in same amount of water has to be identified.

Concept introduction:

• Solubility is defined as capability of solute to get dissolved in solvent. Solvent makes the solute to dissolve and solute undergoes dissolving.
• 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 ${\text{A}}_{\text{3}}\text{B}$ ${\text{K}}_{\text{sp}}\text{=}{\left[\text{A}\right]}^{\text{3}}\left[\text{B}\right]$.
• The solubility product constant ( ${\text{K}}_{\text{sp}}$) is directly proportional to solubility, that is greater the value of ${\text{K}}_{\text{sp}}$ more soluble is the compound.

Correct answer:

Option (b) lead sulphate gives more lead ion while dissolving in water.
