Chapter 12, Problem 12.118QP

(a)

Interpretation Introduction

Interpretation:

Of the three ionic compounds $NaCl,LiCl,KCl$ - The compound with greatest lattice energy has to be identified.

Concept Introduction:

The energy released when gaseous state ions of unlike charges that are infinitely farther apart combine to form a stable ionic solid is called Lattice energy.  Conversely, the energy required to break the electrostatic force of attraction between the ions of unlike charges in the ionic solid and revert them to gaseous state is also termed as Lattice energy of an ionic solid.

(b)

Interpretation Introduction

Interpretation:

Of the three ionic compounds $NaCl,LiCl,KCl$- the compound having greatest energy of hydration has to be identified.

Concept Introduction:

Hydration energy refers to the quantity of energy released when one mole of ion gets hydrated at constant pressure.  Hydration energy of an ion depends upon its ionic size.

(c)

Interpretation Introduction

Interpretation:

The solubility of three compounds $NaCl,LiCl,KCl$ in water has to be described.

(d)

Interpretation Introduction

Interpretation:

The relationship between lattice energy and energy of hydration has to be described.
