Theory 06/Molecular & anomalous/Salt solubility
Solubility Is Hydration Against Lattice
The claim
Whether a salt dissolves is set by the ratio of hydration free energy to lattice energy, so salts with similar lattice energies dissolve very differently.
01Mechanism
Dissolution requires solvation to compensate for breaking the crystal.
02Prediction
Solubility should track the ratio.
03Refutation
Solubility tracking lattice energy would remove hydration.
