Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Water solubility
Administrative data
- Endpoint:
- water solubility
- Type of information:
- read-across from supporting substance (structural analogue or surrogate)
- Adequacy of study:
- key study
- Reliability:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:
- other: Guidance R.7a: "For the determination of the water solubility read-across is usually not possible. However interpolation may still be possible within homologous series." However, values for five other cesium salts are available.
- Justification for type of information:
- For the determination of physical and chemical properties read-across is usually not possible. However, interpolation may still be possible within homologous series.” [ECHA Guidance on Information Requirements and Chemical Safety Assessment, Chapter R.7a: Endpoint specific guidance, Version 3.0, August 2014]. Albemarle Germany has registered various cesium compounds. The physical and chemical properties are comparable and predictable. Therefore, read-across was used.
Please refer to the Read-Across Justification in section 13.

- Water solubility:
- 240 - ca. 1 000 g/L
- Temp.:
- 20 °C
- Remarks on result:
- other: Range of water solubility for five cesium salts (cesium hydroxide monohydrate, cesium iodide, cesium nitrate, cesium chloride and cesium sulphate) is from 240 to >1000 g/L.
- Conclusions:
- Interpretation of results (migrated information): very soluble (> 10000 mg/L)
Studies on water solubility according to OECD Guideline 105 and EU Method A.6 are available for five cesium salts (cesium hydroxide monohydrate, cesium iodide, cesium nitrate, cesium chloride and cesium sulphate). These cesium salts are all very water soluble. Accordingly cesium carbonate is supposed to be very water soluble.

Applicant's summary and conclusion
- Conclusions:
- Interpretation of results (migrated information): very soluble (> 10000 mg/L)
Studies on water solubility according to OECD Guideline 105 and EU Method A.6 are available for five cesium salts (cesium hydroxide monohydrate, cesium iodide, cesium nitrate, cesium chloride and cesium sulphate). These cesium salts are all very water soluble. Accordingly cesium carbonate is supposed to be very water soluble.
In literature a water solubility for cesium hydrogen carbonate is found to be 2090 g/L at 15 °C.
