Results and discussion

pH value
pH value:
6.24
Temp.:
23.7 °C
Concentration:
10 g/L
Remarks on result:
other: suspension

Any other information on results incl. tables

As the water solubility of test item is less than 1 w/v % (10 g/L) so a suspension was resulted.

After stirring the solid particles were allowed to settle for 5 minutes. The pH was measured from the supernatant of the suspension.
