22 ART. 8. — S. KAWAMURA : COAGULATION OF COLLOIDAL 



TABLE 13. 



are two having divalent anions, while one has tetravalent and 

 the remaining one has an anion of possible hexavalency. Thus 

 the rule of Schulze is here brought out much more clearly 

 than in Table 12. 



The limiting value of relative viscosity is also a characteristic 

 quantity for an electrolyte with respect to its coagulative power. 

 But it is perhaps more rational to compare the increase of 

 viscosity '-yum — 1 caused by various electrolytes. The lowest value 

 was found in the case of oxalic acid and ammonium oxalate, 

 being only 0.26. The highest value was reached in potassium 

 ferricyanide, and is about five times as large being 1.24.
