Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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.

Additional information
Despite its name, basic chromium sulfate is acidic. When added to water, a pH in the range of < 2 is established at which the substance is readily soluble in water.
At a neutral or slightly acidic range as provided for water hazard testing (and buffered), the substance hydrolyse fast. The result is chromium(III) oxide that is virtual insoluble as stated in the disseminated REACH registration dossier at ECHA's website. The poorly soluble substance chromium(III) oxide is thus evaluated by the dissolved chromium(III) ion level resulting from the T/Dp at a loading rate of 1 mg/L after 7 and 28 d, respectively, as determined for the (soluble) chromium(III) ion.). Dissolved chromium concentrations of <0.01 µg/L in the T/Dp after 7 and 28 days at pH 6 (i.e. the pH that maximizes the dissolution) were determined.
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).
