Results and discussion

pH value

pH value:

10.1

Temp.:

23.4 °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 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.
