Determining the Heat of Hydration of Lithium Chloride

To calculate the heat of hydration of lithium chloride, we need to consider the lattice energy and the enthalpy of solution of LiCl. These factors play a key role in determining the energy involved in the hydration process.

When analyzing the heat of hydration of lithium chloride, the lattice energy and the enthalpy of solution are crucial components to consider. The lattice energy, which is the energy required to break the ionic bonds in LiCl, is 834 kJ/mol. On the other hand, the enthalpy of solution, which represents the energy change when one mole of LiCl dissolves in water, is -37.0 kJ/mol.

By combining these two values, we can determine the heat of hydration of lithium chloride. The heat of hydration is the energy released when one mole of LiCl ions in the gaseous phase combines with water molecules and forms hydrated ions in solution. It signifies the overall energy change during the hydration process.

The calculation of the heat of hydration involves adding the lattice energy and the enthalpy of solution. By doing so, we arrive at the final answer of 797 kJ/mol for the heat of hydration of lithium chloride. This positive value signifies the energy released during the hydration of LiCl.
