Chapter 13, Problem 22QRT
Interpretation Introduction

Interpretation:

The process of dissolving CaCl2 in water is either endothermic or exothermic has to be determined.

Concept Introduction:

Dissolving ionic solids in liquids: On dissolving ionic solids in water, water molecules surround cations and anions are called hydration.

Hydration enthalpy is defined as the enthalpy change when new attractions form between ions and water-molecule dipoles. Energy always that require to separate the ions from crystal lattice, and energy always released when ions become hydrated because molecular dipoles attract the molecules to the ions.

The relation between the enthalpy of solution as follows,

ΔrHsoln= - lattice energy + ΔrH(cation hydration)+ΔrH(anion hydration).
