Hydration reversible

Equilibrium Ratios fob Hetebocyclio Acids that Hydrate Reversibly... 

A hydrate is a compound that contains water, rather loosely bound. Usually mild heating of the compound can drive off this water of hydration. Addition of water to the anhydrous salt reforms the hydrate (reversible loss/gain of water)...

In a liquid/liquid biphasic system (Figure 9.1a), the enzyme is in the aqueous phase, whereas the hydrophobic compounds are in the organic phase. In pure organic solvent (Figure 9.1b) a solid enzyme preparation is suspended in the solvent, making it a liquid/solid biphasic system. In a micellar system, the enzyme is entrapped in a hydrated reverse micelle within a homogeneous organic solvent... 

Several insulator oxides, such as AI2O3 and Si02, can hydrate reversibly to give hydroxides of the type A1(0H)3, AIO(OH), or Si(OH)4, and, not surprisingly, can catalyze dehydration reactions such as the conversion of alcohols to olefins at elevated temperatures ...
