reagent.
Synthese
The most common procedure for preparing an aqueous chromous sulfate solution employs a reduction of Cr2(SO4)3 with mossy Zn and Hg in water and is used as is. Alternate syntheses start with very pure Cr metal5 or K2Cr2O7. A method for preparing crystalline blue CrSO4.5H2O has been published.
