Ueber die Dissociation der Merkurihaloide. Zeit. phys. Chem., 41, 709. 



By qualitative measurements it was found that when the fol- 

 lowing chemicals are dissolved in strongly acid mercuric nitrate 

 solutions and electrolysed, the halogen increases in concen- 

 tration in the cathode solution : AgCl, HgClj, AgBr, HgBrj, 

 Agl, Hgl2 ; the property increasing in the order mentioned. The 

 preliminary experiments were performed in a U-tube, the solu- 

 tion being solidified with agar agar and the upper half of the 

 tube being filled with silver nitrate; cataphoresis was pro- 

 nounced. The final experiments were made in two beakers 

 connected by a siphon without diaphragms.

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

 zontal piece ; capacity 1300 c.c. ; Pt electrodes ; no diaphragms ; 

 calculation correct. 



The paper further contains measurements of the conductivity 

 of the hydrochloric acid.
