A NOTE ON THE VISCOSITY OF CESIUM SALTS IN GLYCEROL 



WATER MIXTURES. 



BY P. B. DAVIS. 



The study of the viscosity of solution in glycerol and in binary 

 mixtures containing glycerol was begun in this laboratory by Schmidt 

 and Jones 1 a number of years ago. They noted that among the salts 

 measured potassium-iodide solutions lowered the viscosity of water and 

 mixture of glycerol and water up to 50 per cent glycerol, although 

 this salt increased the viscosity of pure glycerol. 



Guy and Jones 1 extended this work in connection with a study 

 of the conductivity and dissociation of electrolytes in glycerol as a 

 solvent and noted that solutions of sodium nitrate, ammonium bromide 

 and iodide, and rubidium iodide all lowered the viscosity of pure 

 glycerol and of its mixtures with water. 



These results led Davis and Jones 1 to investigate the behavior of 

 glycerol of those salts known to decrease the viscosity of water. They 

 measured the viscosity of solution of certain rubidium and ammonium 

 salts in pure glycerol and in mixtures of glycerol with water and found 

 that the salts of rubidium and ammonium iodide produced a phe- 

 nomenal lowering of the viscosity of glycerol, the molecular conduc-
