Decomposition of sodium chloride into a sodium ion and chloride ion re...
Answer:
The energy released when sodium chloride (NaCl) decomposes into sodium ions (Na+) and chloride ions (Cl-) is called the lattice energy. It is a measure of the strength of the forces holding the ions together in a crystal lattice structure.
Lattice Energy:
Lattice energy is the energy required to separate one mole of a solid ionic compound into its gaseous ions. It is a measure of the strength of the ionic bond in the compound. The lattice energy is always exothermic because energy is released when the ions come together to form the crystal lattice, and it is an important factor in determining the stability and properties of ionic compounds.
Explanation:
When sodium chloride is solid, its sodium and chloride ions are arranged in a lattice structure held together by electrostatic forces of attraction. These forces are very strong, and breaking them requires energy. When the solid NaCl is heated to a high temperature, the lattice energy is overcome, and the crystal structure breaks apart, resulting in the formation of gaseous sodium and chloride ions.
The energy released during this process is equal to the lattice energy of sodium chloride, which in this case is 788 kJ/mol. This energy is released as heat and is typically measured per mole of the compound. The lattice energy is a measure of the stability of the ionic compound, with higher lattice energies indicating stronger ionic bonds and greater stability.
Significance:
The lattice energy is an important factor in various chemical processes involving ionic compounds. It affects the solubility of ionic compounds in water, the melting and boiling points of compounds, and their ability to conduct electricity in the molten or aqueous state. The lattice energy also plays a role in the formation of crystal structures and the stability of solid ionic compounds.
Conclusion:
In summary, the energy released when sodium chloride decomposes into sodium and chloride ions is called the lattice energy. It is a measure of the strength of the forces holding the ions together in the crystal lattice structure. The lattice energy is an important factor in determining the stability and properties of ionic compounds.

Lattice enthalpy is the enthalpy change when one molecule of an ionic compound dissociates into its ions and gaseous state. Here sodium chloride is an ionic compound and it decomposes into sodium and chloride ions, so the energy released is lattice energy.
