ON THE CALCULATION OF THE CONDUCTIVITY 



acids. Kohlrausch's latest determinations 1 of the values of the 

 specific molecular conductivity at infinite dilution at 18 C. for 

 the two acids were used, viz. : for hydrochloric acid, 3774, and 

 for sulphuric acid, 3955, both expressed in terms of 10~* times 

 Kohlrausch's new unit (ohm" 1 cm." 1 ). Therefore, the ratio is 

 1.048. 



Table I gives the data, obtained from the conductivity 

 observations, for the drawing of these curves. The concentra- 

 tions are expressed in terms of gramme equivalent per litre 

 at 18C. The atomic weights used are relative to Oxygen 

 (16.00), and the same as employed by 2 Kohlrausch. The specific 

 conductivities are those at 18C, expressed in terms of 1()~ 4 times 

 Kohlrausch's new unit (ohm" 1 cm." 1 ).
