Results and discussion

Preliminary study:
JUSTIFICATION FOR NOT PERFORMING THE STUDY
In accordance with REACH Annex XI, testing may be omitted if testing does not appear scientifically necessary.

Most hydrolysis reactions in inorganic chemistry result in the donation or removal of a proton by water, forming either hydroxide or hydronium ions.

Calcium nitrate is an inorganic salt, very soluble in water. It is a neutral salt; the ions have little tendency to react with water. Hydrolysis is therefore not a relevant parameter for this substance and testing does not appear scientifically necessary.
