WebNov 22, 2004 · According to the ``Hildebrand rule,'' normal liquids should have the same entropy of vaporization at temperatures at which their vapors have the same molal volume. Pitzer has shown that liquids which obey the theory of corresponding states should have equal entropies of vaporization at temperatures at which their ratio of vapor volume to … WebHydrophilic–lipophilic balance (HLB) is the balance of the size and strength of the hydrophilic and lipophilic moieties of a surfactant molecule. The HLB scale ranges from 0 to 20. In the range of 3.5 to 6.0, surfactants are more suitable for use in W/O emulsions. Surfactants with HLB values in the 8 to 18 range are most commonly used in O/W ...
