G. Drago and Wayland, 1965) or to predict K (Edwards, 1954). In either case, the computed values provide a basis for predicting the relative stability of complexes. On the other hand, the proton is a rational choice for a reference Lewis acid in aqueous solution. The proton is small and unpolarizable, and it has a very high lp. g. Ag + and Hg2+). Bases could then be classified according to their reactivity with acids. It is observed that bases in which the donor atoms are relatively small and unpolarizable tend to bond with acids at the proton end of the Lewis acidity scale in preference to acids at the opposite end, and vice versa.

In an outer-sphere complex (sometimes called an ion pair), the ligand resides outside the primary hydration sphere; the ligand is shielded from direct interactions with the cation by the H 2 0 molecules of the primary hydration sphere. A given complex is generally not purely inner-sphere or outer-sphere, but the character of the complex can be dominated by one type or the other in the same sense that bonds are dominated by covalent bonding (inner-sphere; short-range forces with lots of electron sharing between cation and ligand) or electrostatic bonding (outer-sphere; long-range forces with little electron sharing).
