(a)

Interpretation Introduction

To determine: If ionic solute ${\text{CaCl}}_{\text{2}}$ experiences the greatest increase in entropy when $\text{0}\text{.0100}\text{moles}$ of it dissolves in $\text{1}\text{.00}\text{liter}$ of water.

Interpretation: The validation of fact that ionic solute ${\text{CaCl}}_{\text{2}}$ experiences the greatest increase in entropy when $\text{0}\text{.0100}\text{moles}$ of it dissolves in $\text{1}\text{.00}\text{liter}$ of water is to be stated.

Concept introduction: Entropy of the solution increases when the solution contains maximum number of ions in the solution.

(b)

Interpretation Introduction

To determine: If ionic solute $\text{NaBr}$ experiences the greatest increase in entropy when $\text{0}\text{.0100}\text{moles}$ of it dissolves in $\text{1}\text{.00}\text{liter}$ of water.

Interpretation: The validation of fact that ionic solute $\text{NaBr}$ experiences the greatest increase in entropy when $\text{0}\text{.0100}\text{moles}$ of it dissolves in $\text{1}\text{.00}\text{liter}$ of water is to be stated.

Concept introduction: Entropy of the solution increases when the solution contains maximum number of ions in the solution.

(c)

Interpretation Introduction

To determine: If ionic solute $\text{KCl}$ experiences the greatest increase in entropy when $\text{0}\text{.0100}\text{moles}$ of it dissolves in $\text{1}\text{.00}\text{liter}$ of water.
