The standard enthalpy change of hydration of an anhydrous salt Is the enthalpy change when one mole of a hydrated salt Is formed from one mole of the anhydrous salt under standard conditions. [Pg.103]

This should not be confused with the standard enthalpy change of hydration of gaseous ions to form aqueous ions (see page 265 for this material, which is not required for AS level). [Pg.103]

The standard enthalpy changes of hydration and solution can be defined in terms of one mole ofa specified compound reacting completely. [Pg.112]

The energy released when gaseous ions dissolve in water is called the enthalpy change of hydration. [Pg.276]

The enthalpy changes of hydration for calcium ions and chloride ions are described by the equations below ... [Pg.276]

We can calculate the enthalpy change of solution or the enthalpy change of hydration by constructing an enthalpy cycle and using Hess s law (Figure 19.10). [Pg.276]

Figure 19.10 An enthalpy cycle involving lattice energy, enthalpy change of hydration and enthalpy change of solution. Figure 19.10 An enthalpy cycle involving lattice energy, enthalpy change of hydration and enthalpy change of solution.
Determine the enthalpy change of solution of sodium fluoride using the following data lattice energy=-902 kJ mob enthalpy change of hydration of sodium ions =-406 kJmob ... [Pg.276]

Table 19.2 shows the solubility in water of some Group 2 sulfates. The solubility decreases as the radius of the metal ion increases. We can explain this variation in solubility in terms of the relative values of enthalpy change of hydration and the corresponding lattice energy. [Pg.277]

Smaller Ions (with the same charge) have greater enthalpy changes of hydration... [Pg.278]
