Conductivity of Aqueous Solutions. Part VII. 



Table 90. Specific conductance at round temperatures of ammonium acetate 

 solutions containing ammonium hydroxide or acetic acid. 



From the data given in table 90 the hydrolysis of the salt at 218 and 

 at 306 has been calculated in two different ways. 



The first of these is that used by Noyes and Kato (section 73, Part VI) 

 in connection with their hydrolysis experiments at 156. In this method, 

 the following expressions for hydrolysis equilibrium and for the empirical 

 relation of van't Hoff between the ionization and concentration of salts 

 are combined : 



()'= 



(t) 3 = 



(+?) 



L A. 



and thereby the values of Ji and h, the hydrolysis of the salt at concen- 

 tration C in pure water and in the mixture respectively, are calculated. 

 A is the equivalent conductance of completely ionized ammonium acetate ; 

 its values are 741 at 218 and 1020 at 306 (see section 84).
