Results and discussion
pH value
- pH value:
- 6.8
- Temp.:
- 21.8 °C
- Concentration:
- 1 other: %m/v
Any other information on results incl. tables
The pH values measured are shown in the following table:
| Determination | pH Value at 25 °C | Mean pH | ||
| After 1 Minute | After 2 Minutes | After 10 Minutes | ||
| A | 6,25 | 6,53 | 6,79 | 6,78 |
| B | 6,22 | 6,42 | 6,79 | |
pH of the high purity water: 5.87
Ambient laboratory temperature: 21.8 °C
Since the result fell within the range 4 to 10, the determination of acidity or alkalinity by titration was not required.
Applicant's summary and conclusion
- Conclusions:
- Determination of acidity or alkalinity by titration is not required.
- Executive summary:
The pH of the test substance was determined under GLP according to OECD 122 guideline, using a calibrated pH-meter.
Two solutions were prepared at 1%m/v in high purity water, and measurements were recorded after 10 minutes equilibration.
The pH of a 1%m/v aqueous solution temperature of test substance has been determined to be 6.8 (at a temperature of 21.8°C).
