From this result, however, we see that the ionisation cannot diverge 
very widely from the normal value, as the hydrolysis in half-normal solution 
is quite what one would expect it to be. 
The speed of the ions is another factor in the calculation which is 
assumed to he quite normal without any particular justification. The 
viscosities of sixteenth- and of half-normal anthranilic solutions were there- 
fore compared with those of solutions of hydrochloride acid at the same 
dilution.

Even in half -normal solution we see that the difference is not nearly 
enough to account for the great reduction in the conductivity. It may
