Hydration enthalpy vs lattice enthalpy
Web12 aug. 2024 · The enthalpy of the solution involves two processes, i.e., lattice energy and enthalpy of hydration. The lattice energy of NaCl is the energy released when Na + and Cl − ions come close to each other to form a lattice. NaCl (s) → Na + (g) +Cl − (g) (I) The enthalpy of hydration takes place when there is a dispersal of gaseous solute in water. Web20 apr. 2024 · Solubility of a compound is depends on the co-relation between lattice enthalpy and hydration enthalpy. If the hydration enthalpy is equal to or greater than the lattice enthalpy , then the salt is water soluble. More the hydration enthalpy as compared to lattice enthalpy more will be the solubility of salt in water.

Web26 nov. 2024 · You can't use the original one, because that would go against the flow of the lattice enthalpy arrow. This time both routes would start from the elements in their standard states, and finish at the gaseous ions.-411 + LE = +107 + 496 + 122 - 349. LE = +107 + 496 + 122 - 349 + 411. LE = +787 kJ mol-1. WebNa (s) +1 Cl2 → NaCl (s) ΔH = - 411KJ. Lattice enthalpy is a measure of the strength of the forces between the ions in an ionic solid. The greater the lattice enthalpy, the stronger the forces, and higher is the energy released in the environment when the crystal is formed. This energy is released when bonds are made and is needed to break ...
