Ions in solution preparation

The scale frequently used to characterize the solvating power (the acceptor strength) of an acceptor solvent is the Kosower Z scale [Ko 58]. The procedure is based on the fact that the cation of the l-ethyl-4-carbomethoxypyridinium iodide ion pair used as the model system is not an electron pair acceptor, while the iodide anion is capable of hydrogen bonding. Consequently, the extent of ion pair formation between the l-ethyl-4-carbomethoxypyridinium cation and the iodide ion in solutions prepared with various solvents depends on the solvation of the iodide ion.
