FIG. 34. CONDUCTIVITY OF CALCIUM NITRATE IN MIXTURES 

 OF ACETONE AND METHYL ALCOHOL AT 0. 



Tables 58 and 59 (figs. 34 and 35), for calcium nitrate in mixtures of 

 acetone and methyl alcohol, give a pronounced maximum in conductivity at 

 high dilutions. It will be recalled that Jones and Carroll obtained a mini- 

 mum conductivity with this salt, in mixtures of ethyl alcohol and water, 

 only at low temperatures and at high dilution. It should be noted that 

 calcium nitrate is very slightly dissociated in acetone, and that the maximum 

 occurs in the 25 per cent mixture. 



The temperature coefficients of conductivity decrease with the dilution, 

 and they are also less in the mixtures than in the pure solvents, the minimum 

 appearing in the 75 per cent mixture.
