Chapter 18, Problem 92SAE

Interpretation Introduction

(a)

Interpretation:

Important distinctions between solubility and solubility product constant should be described.

Concept introduction:

Solubility product constant, K_sp is the equilibrium constant for a solid substance dissolving in an aqueous solution. There is a definite relationship between molar solubility and solubility product.

Interpretation Introduction

(b)

Interpretation:

Important distinctions between common-ion effect and salt effect should be described.

Concept introduction:

Common ion and salts both affect on the solubility of a solid. Common ion decreases the solubility while salts increase the solubility of a substance.

Interpretation Introduction

(c)

Interpretation:

Important distinctions between ion-pair and ion product should be described.

Concept introduction:

Ion pair formation is a cation and anion are in intimate contact in solution, rather than completely dissociate in the solution

Ion product is the product of ion concentrations in the solution raised to the power of their stoichiometric coefficients at any concentration.
