COMPLEX SOLUTIONS.—ARCHIBALD, | 47 
ions in the mixture is meant the number of dissociated gramme- 
equivalents of either electrolyte in any volume of the mixture 
divided by the volume of that portion of the mixture which may 
be regarded as occupied by it. The dilutions of the electrolytes 
in the mixture are the volumes of such portions divided by the 
number of gramme-equivalents of the electrolytes they contain. 
The product of these two quantities for each electrolyte gives 
the ionization coefficient of such electrolyte in the mixture.) 
The data of the other columns are sufficiently specified by the 
headings.
