Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.
The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Description of key information
Photodegradation
There is no evidence for photodegradation of ammonium sulfate. However, ammonium sulfate may be formed in atmospheric aerosols (occurrence predominantly in the fraction < 2.5 μm) from reaction between ammonia and sulfuric acid (from SO2 emissions). SO2 concentrations control the ammonium sulfate formation (Scott and Cattell, 1979; Gmur, Evans and Cunningham, 1983).
Hydrolysis
In aqueous solution, ammonium sulfate is completely dissociated into the ammonium ion (NH4+) and the sulfate anion (SO4 2-). Hydrolysis of ammonium sulfate does not occur.

Additional information
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
