Hydrated chromium(III) sulfate, Cr 2 (SO 4) 3 ·18H 2 O, (CAS #13520-66-6) is a violet solid that readily dissolves in water to give the metal aquo complex, [Cr(H 2 O) 6] 3+. The formula of this compound can be written more descriptively as [Cr(H 2 O) 6 ] 2 (SO 4 ) 3 ·6H 2 O. Six of the eighteen water molecules in this formula unit are water ...
Chrome alum or Chromium(III) potassium sulfate is the potassium double sulfate of chromium. Its chemical formula is KCr(SO 4) 2 and it is commonly found in its dodecahydrate form as KCr(SO 4) 2 ·12(H 2 O). It is used in leather tanning. [1]
A tetrahedral coordination of chromium(III) has been reported for the Cr-centered Keggin anion [α-CrW 12 O 40] 5–. [11] Chromium(III) hydroxide (Cr(OH) 3) is amphoteric, dissolving in acidic solutions to form [Cr(H 2 O) 6] 3+, and in basic solutions to form [Cr(OH) 6] 3−. It is dehydrated by heating to form the green chromium(III) oxide ...

Chromium(II) sulfate is an inorganic compound with the chemical formula Cr S O 4. It often comes as hydrates CrSO 4 ·nH 2 O. Several hydrated salts are known. The pentahydrate CrSO 4 ·5H 2 O is a blue solid that dissolves readily in water. Solutions of chromium(II) are easily oxidized by air to Cr(III) species.
Chromium(III) oxide is amphoteric. Although insoluble in water, it reacts with acid to produce salts of hydrated chromium ions such as [Cr(H 2 O) 6] 3+. [10] It is also attacked by concentrated alkali to yield salts of [Cr(OH) 6] 3−. When heated with finely divided carbon or aluminium, it is reduced to chromium metal: Cr 2 O 3 + 2 Al → 2 Cr ...
