Solution chemistry, solubility and solubilization
... water for each of the two compounds. This means that by solvent manipulation we can increase the solubility of these compounds a millionfold. If instead of phenanthrene and anthracene we had, say, drug A and drug B, could we solubilize drug B to the same level of drug A? The answer is no. Anthracene ...

This is because the mixing of two, or more, species alters the molecular interactions experienced by the molecules being mixed; thus, the internal energy and hence enthalpy will change. There may also be a change in volume when two ...

Equilibrium chemistry
Equilibrium chemistry is a concerned with systems in chemical equilibrium. The unifying principle is that the free energy of a system at equilibrium is the minimum possible, so that the slope of the free energy with respect to the reaction coordinate is zero. This principle, applied to mixtures at equilibrium provides a definition of an equilibrium constant. Applications include acid-base, host-guest, metal-complex, solubility, partition, chromatography and redox equilibria.
