that the depressing effect of these three salts on gelatin chloride 

 is practically exclusively a function of the concentration of the

FIG. 31. The relative depressing effect of equal molecular concentrations 

 of NaCl, Na2SO4, and Na4Fe(CN)e on the relative viscosity of a gelatin chloride 

 solution of pH 3.0 is approximately as 1:4: 16. 



Cl ion, while no augmenting effect of the cation is noticeable. 

 This observation disposes of vague hints found in the literature
