OF SALTS IN ETHYL ALCOHOL AND WATER. 97 



also conclude that the same reasoning may be applied to the latter; in 

 other words, there is a greater change in the viscosity of the water than 

 of the alcohol. 



8. The decrease in the conductivity of potassium iodide with the in- 

 crease in the percentage of alcohol, is more rapid than the decrease for 

 sodium iodide, due no doubt to the greater atomic volume of the former. 

 p| 9. Hydration has practically no effect on the conductivity at any one 

 temperature. With rise in temperature, however, the breaking down 

 of the slightly hydrated ions causes a small increase in the temperature 

 coefficients in most of the solutions containing water. In alcohol the 

 temperature coefficients are a linear function, and therefore there is no 

 alcoholation. 



10. As the temperature rises the curves tend to become more and 

 more nearly a linear function. We attribute this to the fact that as 

 the temperature rises the fluidity curves also tend to become more 

 nearly linear.
