Applicant's summary and conclusion
- Conclusions:
- Interpretation of results (migrated information): slightly soluble (0.1-100 mg/L)
The solubility of the test item in deionized water (pH 5.9) at 25°C is (average solubility - mg/L):
Lead: 21.6; Copper: 10.8; Resorcylic acid: 10.6; Salicylic acid: 35.5.
As these values are close, a weighted mean value may be considered if necessary for calculations.
