Goldschmidt thought that it was evident, after carrying his dilutions 

 to 5,120 liters, that A could not be reached by ordinary experimental 

 methods. He attempted to calculate A for these organic salts and 

 expected to obtain the relative velocity of the organic anion from the 

 salt and introduce the same into the equation 



To determine A for the organic salt he made use of the Kohlrausch 

 formula 1 



in which A is the unknown conductance at infinite dilution, A the 

 conductance at a known dilution v, and a an unknown constant. Two 

 equations involving the use of different A values are equated, the A 

 being the same in both cases, and the expression solved for the value a. 

 Once having this, it is a simple matter to solve for A a in one of the two
