Results
Results of duplicate measurements were:
#1
44.39 ± 0.05 mN/m
#2
44.51 ± 0.03 mN/m
Taking into account the different values and their nominal uncertainty, the uncertainty of the mean value (44.5 mN/m) is estimated as 0.1 mN/m.
The surface tension of n-butylparaben at 90% of the saturation and 20 °C is 44.5±0.01 mN/m.
The substance is surface active.
