The effect of the solution of various metallic ions at varying pH upon the wettability of stearic acid surface has been studied. These ions are adsorbed by stearic acid surface in characteristic pH region and are classified into the following three groups, according to their effects on wettability.
(1) (Remark: Graphics omitted.)
(2) (Remark: Graphics omitted.)
(3) (Remark: Graphics omitted.)
The classification has been based upon the structural characteristics of the ions, especially the co-ordination tendency of the ions. The theory of overturning of molecules in surface layer is also one of the probable supports of these opinions.
