40. SUMMARY OF THE EQUIVALENT-CONDUCTANCE VALUES. 



The separate conductance values given in table 19 were all corrected so 

 as to correspond to the uniform temperatures of 18, 100, 156, 218, 281, 

 and 306 by means of temperature-coefficients obtained by plotting those 

 values. The so-corrected equivalent conductances are summarized in 

 table 20. The concentration is expressed in milli-equivalents per liter at 

 4. In the columns headed "Initial" are given the equivalent conductances 

 obtained from the measurement at the temperature in question before 

 going to the higher temperatures ; while in the columns headed "Final" are 

 given the equivalent conductances obtained after returning to the tempera- 

 ture in question from the higher ones. From a comparison of the separate 

 initial values at any temperature and concentration the degree of agree- 

 ment of determinations made at different times, and often with differ- 

 ent solutions, will be seen. A comparison of the initial and final values 

 in the separate experiments shows the contamination that resulted from 

 the heating.
