UF CERTAIN ORGANIC BASES AND ACIDS. — CREIGHTON. 159 



On accoimt of the readiness with A\'hich acetoplienone solu- 

 tions of bromcamplior-carboxylic acid decompose in tlie pres- 

 ence of small cjuantities of organic bases^, it Tvas not possible 

 to measure the conductivity of salts of this acid. In order to 

 obtain some idea of the order of the conductivity of the salts 

 of bromeamphor-carboxylic acid with weak bases, an 

 acetophenone solution, which was 0.3305 molar with respect 

 to acid and 0.0113 molar with resj)ect to conine. was prepared 

 and its conductivity immediately determined. The specific 

 conductivity of this solution was foimd to be 65.0- 10"; its 

 molecular conductivity was, therefore, 196.6 -lO""*. 



The conductivities given in the foregoing table have been 

 corrected for the conductivity of the solvent. 



In the following table there is given the specific conductiv- 

 ity of half normal acetophenone sfolutions of a number of 

 weak organic bases; the specific conductivity of half normal 

 acetophenone solutions of the salts of these bases with camphor- 

 carboxylic acid and. lastly, the specific conductivity of half 

 normal water solutions and the dissociation constants of some 

 of the bases. In this table the bases are placed in the order 

 of their dissociation constants in water solution,
