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.
