TABLE 158. 

 SPECIFIC VISCOSITY.* 



I6 3 



* In the case of solutions of salts it has been found (vide Arrhennius, Zeits. fur Phys. Chem. vol. i, p. 285) that 

 the specific viscosity can, in many cases, be nearly expressed by the equation /u. =:MI"> where fx t is the spec 

 for a normal solution referred to the solvent at the same temperature, and n the number of gramme molecules 

 solution under consideration. The same rule may of course be applied to solutions stated in percentages 

 gramme molecules. The table here given has been compiled from the results of Reyher (Zeits. fur Phys. Lhem. vol. 2, 

 p. 749) and of Wagner (Zeits. fur Phys. Chem. vol. 5, p. 3') and illustrates this rule. The numbers are all i
