Dissolution can be viewed as occurring in three steps:

  1. Breaking solute-solute attractions (endothermic), see for instance lattice energy in salts.
  2. Breaking solvent-solvent attractions (endothermic), for instance that of hydrogen bonding.
  3. Forming solvent-solute attractions (exothermic), in solvation.
