Applicant's summary and conclusion
- Conclusions:
- The pH of a 1 M aqueous solution of the test material was determined to be 13.74 at 25 °C.
- Executive summary:
The pH of a 1 Molar aqueous solution of the test material was determined in accordance with the standard ASTM E70 'Standard Test Method for pH of Aqueous Solutions with the Glass Electrode '.
A 1 M aqueous solution was prepared using 1.392 g of the test material, made up to a 10 mL volume with distilled, deionised water.
The pH was measured using a Metrohm Model 827 pH meter, with a Metrohm Combination Glass Electrode. The pH meter and electrode were calibrated using buffers at pH 4, 7, 9 and 10.
The pH of a 1 M aqueous solution of the test material was determined to be 13.74 at 25 °C.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
