Results and discussion

Surface tension
Key result
Surface tension:
58.11 mN/m
Temp.:
20 °C
Conc.:
90 other: percent of solubility
Remarks on result:
other: overall mean of first measurement (6 values measured) and second measurement (6 values measured).
Remarks:
It was intended to prepare a 1 g/L solution. However, as the test item did not dissolve completely, the saturated solution was filtered and diluted to receive a solution with a concentration of about 90% of the solubility. The concentration refers to nominal concentration of the test item.

Any other information on results incl. tables

The detailed results of two measurements are summarized in the table below.
