TABLE VI. 

 Diffusion of iodine in potassium iodide solution. 

 Normality of KI3, 1/20. Normality of KI, 4.5. 

 All cylinders in thermostat at 25°. 



(Work of the author under the direction of Dr. Graham Edgar). 



* In this case 2 drops too much were drawn off with the layer titrated. Making 

 an approximate correction, we obtain the unbracketed value for K given above. 



This table and the one preceding one were especially difficult to obtain owing 

 to the exceedingly small difference between the specific gravity of the KI solution 

 and that containing the iodine. 



T.4BLE VII. 

 Diffusion of iodine in comparison with viscosity and density of the KI solution at 25° 



Z, Viscosity relative to water at 25°. 



Z, Viscosity relative to water at 0°. 



jj, Absolute viscosity, C.G.S. units. 



F, Fluidity, i.e., reciprocal of Z. 



* Obtained by Dr. Edgar alone. 



(Except as noted, work of Dr. Edgar and the author).
