Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.

The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Description of key information

In accordance with REACH Regulation (EC) No. 1907/2006, Annex XI, section 1.1.1, the performance of a test for hydrolysis as function of pH is scientifically unjustified. The study does not need to be conducted as cesium iodide completely dissociates in water forming a cesium cation and the corresponding iodide. Both, the cation and the anion are stable in the aquatic environment. The dissociation constant of cesium iodide was determined according to OECD Guideline 112 with the titration method. The dissociation constant was not determinable because cesium iodide is a strong electrolyte (see IUCLID section 4.21 Dissociation constant).
