Hildebrand solubility parameter water

WebThe Hildebrand Solubility Parameter. It is the total van der Waals force, however, which is reflected in the simplest solubility value: the Hildebrand solubility parameter. The … WebThe Hildebrand solubility parameter is defined as the square root of the cohesive energy density given by the following equation: δ = (E / V)1/2 Where E is the energy of vaporization, V = Volume and δ is the Hildebrand Solubility Parameter. This value is generally reported in MPa½, but is also 2.0455 times larger than (cal/cm3)½.
