Difference Between Lattice Energy and Hydration Energy

WebAs seen above, sodium chloride has a heat of solution of + 4 kJ/mol. The reason this value is positive and small is because its lattice energy is only slightly larger than the heat of hydration. For potassium fluoride, the heat of solution is -18 kJ/mol which is due to the fact that the lattice energy is smaller than the heat of hydration. WebThe energy required to separate the ions in a crystal lattice into individual gaseous ions is known as lattice energy. Lattice energy depends on the strength of interactions between cations and anions in the lattice, which we can estimate using Coulomb's law: Fₑ = (q₁q₂)/r².According to this equation, stronger interactions occur between ions with larger … WebAs seen above, sodium chloride has a heat of solution of + 4 kJ/mol.
