The Nature of a Solution ot Iodine in Aqueous Potassium Iodide. Jour. 

 Chem. Soc. Sj, 1305. 



The authors deduce from the resuUs of the comprehensive 

 study of sohitions of iodine in potassium iodide by previous inves- 

 tigators that KI and KI., are equally " strong " (t. <?., the dissocia- 

 tion constants are equal). Proceeding from this, and making 

 use of the equilibrium constant for I^ + I' = I^', they show that 

 the relative rates of the I3' and I' ions maybe deduced from the 

 migration value (that of KI being known) and independently by 

 the measurement of the conductivity of potassium iodide solu- 

 tions with and without the addition of iodine. 



Apparatus : too complex for description without a figure ; Pt 

 electrodes; no middle portion; no diaphragms; 25°C. ; the 

 results are based (inaccurately) on constant volume of solution 

 instead of constant weight of water. The KI was from 0.025 m 

 to 0.5 m, the added l.^ 0.0075-0.06 m. 



The transport method gave as ratio of the mobilities of the I3 

 and the I ions 0.556; the conductivity method 0.553.
