Chapter 11.2, Problem 1RC

Interpretation Introduction

Interpretation: It should be determined for the more negative enthalpy of hydration for the given molecule.

Concept introduction:

Hydration enthalpies:

The heat energy released when new bonds are made or formed between the ions and water molecules is known as the hydration enthalpy of the ion.

The hydration enthalpy is defined as the enthalpy change when 1 mole of gaseous ion dissolve in sufficient water to give an infinitely dilute solution.

Hydration enthalpies are always negative.
