Where ß is the dihition, U tlie molecular conductivity. 

 Measurements were made at the temperature of 25°C. The follow- 

 ing table shows the variation of the conductivity with time.

As seen in the above tables the carbonatotetrammine cobaltic 

 sulphate is stable in water and shows little variation of conductivity 

 with the dilution. The molecular conductivity at the dilution 

 of èOO- 1600 is about 100. The conductivity of the aquopentam- 

 mine cobaltic sulphate varies more with its dilution than that of 

 the carbonatotetrammine cobaltic salt. The dilution from 800 to
