LEWIS AND WHEELER. — CONDUCTIVITY OF SOLUTIONS.

TABLE III. 

 Series 2. 



The result9 contained in Series 2 are expressed graphically in Figure 

 2, the lower points representing the values at 160°, the upper those at 

 140°. It is evident that the values of M increase rapidly with the con- 

 centration. This phenomenon, although it has never been observed in 

 aqueous solutions, is not rare in the case of other solvents. The figure 

 shows further that between C = 0.1 and C = 1.0, M increases linearly 

 with the concentration. The form of that portion of the curve lying 

 below C = 0.1 deserves little attention, as the values here are much 

 affected by the correction made for the original conductivity of the iodine, 

 and are thus liable to large errors, even assuming that our method of 

 making the correction is entirely correct in theory. 



Above C = 1.0 the line shows the beginning of a curvature which 

 becomes much more pronounced at slightly higher concentration.
