Registration Dossier
Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Hydrolysis is irrelevant for sodium sulphate as it dissociates into Na+ and SO4 2- and is very stable in water.
Key value for chemical safety assessment
Additional information
Hydrolysis is a chemical process in which a molecule is split in two parts by the addition of water.
Sodium Sulphate dissociates into Na+and SO42-in water. It is well known that sulphates are very stable in aqueous solutions (Hollemann and Wiberg, 1995). Therefore hydrolysis is irrelevant in case of Sodium Sulphate.

Stability in Water
In water sodium sulfate completely dissociates into sodium and sulfate ions. The ions cannot hydrolyze
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.
