Abstract
Salting constant measurements have been made on 1-naphthol, 2-naphthol, and 1-NO-2-naphthol using a distribution method at 298 K. In general, the order of the salting effect is similar to that for other acidic nonelectrolytes. However, a net salting-in is observed in the pair 1-NO-2-naphthol – NaF, and such an effect is interpreted by postulating hydrogen bonding. A comparison of results with those found for benzene, naphthalene, phenol, etc …, reveals that salt effects for organic nonelectrolytes depend upon the solute size for a given salt.Experimental ks are compared with those calculated using various salting theories. The agreement is not quantitative.Keywords
