Administrative data
Link to relevant study record(s)
- Endpoint:
- water solubility
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- January 1998- April 1998
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- guideline study
- Remarks:
- The test was conducted following OECD Guideline 105, EEC directive A.6 and ,,Richtlinien fiir die Prüfung von Pflanzenschutzmitteln im Zulassungsverfahren Teil I, 1-2, B/7, 26".
- Qualifier:
- according to guideline
- Guideline:
- OECD Guideline 105 (Water Solubility)
- Deviations:
- yes
- Remarks:
- The quantity of test substance in the main test to saturate the used volume of water was lower than 5 of the amount determined in the preliminary test because in higher concentrations of the test substance the volume of supernatant water was too low
- GLP compliance:
- yes
- Type of method:
- flask method
- Water solubility:
- 317.76 g/L
- Temp.:
- 20 °C
- pH:
- 9.7

- Water solubility:
- 125.76 g/L
- Temp.:
- 20 °C
- pH:
- 9.7
- Remarks on result:
- other: Determination of saturation concentration of the test item calculated by the response of 2-Hydroxy-2-sulfonato acetic acid, disodium salt
- Water solubility:
- 727.41 g/L

- 9.7
- Remarks on result:
- other: Determination of saturation concentration of the test item calculated by the response of sodium sulphite
- Details on results:
- The solubility of the test item at 20 °C was determined to be 125,760 mg/L.
This means that 125.76 g of the test item will be dissolved completely in water.
The sustance is considered to be "very soluble". - Conclusions:
- Interpretation of results (migrated information): very soluble (> 10000 mg/L)
The solubility of the test item at 20 °C is 125.76 g/L - Executive summary:
The solubility of the test item at 20°C was 125.76 g/L. This means that 125.76 g of the test item will be dissolved completely in 1 L water.
The solubility of the main constituent, 2-Hydroxy-2-sulfinato acetic acid, disodium salt at 20 °C was determined to be 317.8 g/L.
Reference
Since the test item is a multi-cosituent substance, the other solubilites by reponse of the components also have been determined
Solubility (average values) | Na2[SOO-CHOH-COO] | Na2[SOOO-CHOH-COO] | Na2SO3 |
in g/L (at 20 °C) | 317.1 | 125.8 | 727.4 |
in g/L (at 4 °C) | 316.7 | 137.8 | 428.7 |
The mean pH of the saturated solution at 20 °C was determined to be 9.68. The mean density at 20 °C was 1.2678 g/mL.
The mean pH of the saturated solution at 4 °C was determined to be 9.72. The mean density at 20 °C was 1.2165 g/mL.
