Cobalt Chloride in Water; Conductivity and Dissociation. 



The conductivities of solutions of cobalt chloride at the temperatures 

 35, 50, and 65 were determined, and the approximate dissociations at 

 these temperatures calculated. The hydrolysis especially at the more 

 elevated temperatures made it impossible to calculate the dissociations 

 accurately, v is the volume, pv the molecular conductivity. 



Cobalt Bromide in Water; Conductivity and Dissociation. 



Cobalt Nitrate in Water; Conductivity and Dissociation. 



Cobalt nitrate, like cobalt chloride, is somewhat hydrolyzed in dilute 

 solutions. The dissociations a are, therefore, only approximations.
