Results and discussion
Surface tension
- Surface tension:
- 72.3 mN/m
- Temp.:
- 20.6 °C
- Conc.:
- 1.09 g/L
Applicant's summary and conclusion
- Conclusions:
- The surface tension of a saturated solution of UC-136 in water was determined to be 72.3 mN/m.
Therefore, a saturated solution of UC-136 in water does not lower the surface tension.
