ResumoThe solubilities and the peculiar temperature dependence of hydrophobic substances in water were coherently explained in 1977 taking into account 1) the strong solidification tendency of water, 2) the large enthalpy of solution evident from the low solubilities, 3) the large entropy of dilution due to the small solubility, and 4) the large negative enthalpy and entropy of iceberg formation. As far as the author knows, there is no paper contradicting this interpretation. The present paper reviews the thermodynamic reasoning and experimental evidences confirming the interpretation. The phenomena are now much better understood due to new experimental evidences.
