THE EQUIVALENT CONDUCTIVITY OF SALTS, ACIDS AND BASES IN 



AQUEOUS SOLUTIONS 



In the following table the equivalent conductance is expressed in reciprocal ohms. The con- 

 centration is expressed in milli-equivalents of solute per liter of solution at the temperature to which 

 the conductance refers. (In the cases of potassium hydrogen sulphate and phosphoric acid the 

 concentration is expressed in milli-formula-weights of solute, KHSO4 or H3PO4, per liter of solu- 

 tion, and the values are correspondingly the modal, or "formal," conductances.) Except in the 

 cases of the strong acids the conductance of the water was subtracted, and for sodium acetate, 

 ammonium acetate and ammonium chloride the values have been corrected for the hydrolysis of 

 the salts. The atomic weights used were those of the International Commission for 1905, referred 

 to oxygen as 16.00. Temperatures are on the hydrogen gas scale.
