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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Additional information
Sodium hydrogensulfate:
Sodium hydrogensulfate readily dissociates in water with an acidic reaction, resulting in hydrogensulfate anions and sodium cations. The hydrogensulfate anion (pKa=1,991) partly dissociates further to the sulfate anion and the hydrogen cation, which is responsible for the acidic reaction. All resulting ionic species are stable in water and not subject to any form of hydrolysis.
Sodium sulfate:
In water sodium sulfate completely dissociates into sodium and sulfate ions, both of which are stable in aqueous media and not subject to hydrolysis.

Photodegradation
Based on the chemical properties of sodium hydogensulfate, photodegradation is not a relevant route of degradation.
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.
