- Conclusions:
- Interpretation of results (migrated information): very soluble (> 10'000 mg/L)
Water Solubility of the test material was determined to 785.8 +/- 0.11 g / L at 20°C - Executive summary:
with a solubility of 785.8 g/ L ths test material is higly water soluble
Reference
pretest:
29.022 g of test material in 20.04 mL deminaeralized water were not fully soluble.
Flask #1:
85 g test material in 50 mL demineralized water, difficult to stir. Assay result iodometric: 57.62 and 57.50, mean value 57.56 % w/w
Flask #2:
80 g test material in 50 mL demineralized water, easy to stir. Assay result iodometric: 57.45 and 57.45, mean value 57.45 % w/w
Flask #3:
73.7 g test material in 50 mL demineralized water, difficult to stir. Assay result iodometric: 57.62 and 57.51, mean value 57.565 % w/w
Rel. density of saturated solution at 20°C: 1.3654
Description of key information
Solubility was measured according OECD /EU Guideline
Key value for chemical safety assessment
- Water solubility:
- 785.8 g/L
- at the temperature of:
- 20 °C
Additional information
Three measurement of the flask method were carried out with a deviation of less than 0.1% rel.
