 Elektrochem., S, 71 (from Jour. Russ. Phjs. Chem. Ges., JJ, 480, 592). 



For apparatus see Kistiakowsk}-, 1890. From the author's 

 measurements of Ag3Cr(C20j3, K,Fe(CN)g and K3Co(CN)g he 

 concludes that the complex ions obey Kohlrausch's Law. Data 

 are not quoted in the reviews.

Apparatus : a pair of vertical U-tubes connected by a hori- 

 zontal piece ; capacity 1050 c.c. ; Pt electrodes ; no diaphragms. 

 The solutions were kept neutral at the electrodes by adding 

 acid and alkali during the electrolysis. The electrolyses were 

 carried out at 25° C. In the fourth column are given the 

 changes in the middle portions. The method of calculation is 

 correct.

Lecture experiments Nos. 5, 6, and 7 employ rather complex 

 mixtures to show qualitatively by the direct method the migra- 

 tion of the ions of copper chromate, potassium hydrate, a mix- 

 ture of hydrochloric acid and cupric chloride, and of potassium 

 silver cyanide.
