Conductivity and Fluidity of Solutions. 483 
In solution 1, there is no combination of the ions as the 
temperature rises, so that here, too, any change iw the value 
ay 
of F will indicate a change in the ionic atmospheres. . Here 
also the decrease is from 1:11 to 1. For this solution, F has 
the same values as for the solution just considered, but C has 
smaller values throughout because there are fewer carriers of 
electricity, although the atmospheres work out to have the 
same values as in the other solution throughout. 
Solution 2 has the same increase for the radii of the atmo- 
spheres if the ionization coefficients in our table have the 
physical meaning which that name should imply, but here 
the atmospheres at any particular temperature are smaller by 
one per cent. If, however, the atmospheres remain of 
constant radius for all solutions, at any particular temperature, 
the figures under 2 in the table of ionization coefficients must 
be increased by 1 per cent. throughout to have their physical 
meaning.

For the stronger solutions the ratio 1:11 to 1 remains 
throughout, but there is nothing to indieate how the ionic 
atmospheres vary with the concentration.
