Applicant's summary and conclusion

Conclusions:
Interpretation of results (migrated information): other: Solubility varies with pH.
At pH 3.1, solubility of copper oxychloride was found to be >101 g/L as salt form and > 60.1 g/L as copper. At pH 6.5, solubility of copper oxychloride was found to be 1.19x10-3 g/L as salt form and 7.08x10-4 g/L as copper. At pH 10.1, solubility of copper oxychloride was found to be ≤5.25x10-4 g/L as salt form and ≤3.12x10-4 g/L as copper.
