WebHydrated chromium (III) sulfate, Cr 2 (SO 4) 3 ·15 (H 2 O), (CAS #10031-37-5) is a green solid that also readily dissolves in water. It is obtained by heating the 18-hydrate material above 70 °C. Further heating yields the anhydrous sulfate. A variety of other chromium (III) sulfates are known, but also contain hydroxide or oxide ligands.
