MOLECULAR CONDUCTIVITY OF AMIDOSULPHONIC ACID. 261 



c =;.//. 



The results obtained are given below, in which r= resistance of 



the rheostat and R — ratio of the two arms of the scale, — T .

Mean 149.55. 

 Hence, c=/l/7=2.594x 10- s x 0.14955 x 10 3 = 0.387933. 



Specific conductivity of water. Taking advantage of the cold 

 weather at the time, I purified the distilled water employed for making 

 and diluting the solutions by freezing a portion of it. The ice 

 formed was melted and used in all the determinations. Its specific 

 conductivity was determined with the following results :

As the molecular conductivity of the solutions was determined 

 for r = 32, 64, 128, 256, 512, and 1024 liters, the corrections for the 

 conductivity of water for the respective dilutions are — 

 o„=0.06, 0.12, 0.24, 0.49, 0.97, and 1.94 ;
