 Walling 34 suggests a similar definition for the acid strength as the ability of the surface to convert an adsorbed neutral base to its conjugate acid where Ho =-log(aAfB/ fAfi) (2) Where now, aA is the activity of the Lewis acid or electron acceptor.

...(4) need not be considered at this time. According to Walling's extension of the Hammett H0 method, the ability of the surface to convert an adsorbed neutral base to its conjugate acid is taken as a measure of the acid strength of the surface. Walling employed five indicator dyes covering... | |

...examined using a flow Hammett indicator method in Table 3. The acidic strength of a solid is defined as the ability of the surface to convert an adsorbed neutral base into its conjugate acid. Thus, the color of suitable indicators absorbed on a surface can give a measure... | |
