Conductivity of Aqueous Solutions. Part IX. 



derived as just described, and adding that of the H + ion. The A - values 

 for the ammonium salt were derived from direct conductance measure- 

 ments which will be presented and discussed in section 103. For the 

 equivalent conductance of the H + ion at 18 the value (315) derived 

 from the measurements of Goodwin and Haskell* upon very dilute acid 

 solutions was adopted ; while at and 25 the values 224.3 and 318.5, 

 respectively, were obtained from this one at 18 by means of Kohlrausch's 

 temperature-coefficients just referred to.
