Results and discussion
Surface tension
- Remarks on result:
- other: From the experience with five cesium salts it can be concluded that the surface tension of cesium hydrogen carbonate is between 69.2 and 72.8 mN/m (20 °C; 1.0 g/L).
Applicant's summary and conclusion
- Conclusions:
- Cesium salts change in a concentration of 1.0 g/L change the surface tension of water marginally. From the experience with five cesium salts it can be concluded that the surface tension of cesium hydrogen carbonate is between 69.2 and 72.8 mN/m (20 °C; 1.0 g/L).
- Executive summary:
“c
Even if different cesium salts do not fit in the concept of homologous series, there are values for five cesium salts in water at 20 °C according to OECD 115 and EU A.5 available.
Cesium iodide 69.2 mN/m (at 1.0 g/L)
Cesium hydroxide *H2O 71.1 mN/m (at 1.0 g/L)
Cesium sulphate 71.1 mN/m (at 1.0 g/L)
Cesium nitrate 72.5 mN/m (at 1.0 g/L)
Cesium chloride 72.8 mN/m (at 1.0 g/L)
