TABLE 413.— 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 sulfate and phosphoric acid 

 the concentration is expressed in milli-formula-weights of solute, KHS0 4 or H3PO4, per liter 

 of solution, and the values are correspondingly the modal, or "formal," conductances.) Except 

 in the cases of the strong acids the conductance of the water was substracted, and for sodium 

 acetate, ammonium acetate and ammonium chloride the values have been corrected for the 

 hydrolysis of the salts.
