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 ...
Soda Industry now is the leading producer of chromium compounds and the 4th greatest producer of sodium compounds (such as sodium dichromate (Na 2 Cr 2 O 7), basic chromium sulfate ([Cr 2 (H 2 O) 6 (O H) 4] S O 4) and chromic acid (H 2 Cr O 4) with an annual production of 2.2 million metric tons in Europe.
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.
A sulfate-based bath that uses insoluble catalytic anodes, which maintains an electrode potential that prevents oxidation. The trivalent chromium-plating process can plate the workpieces at a similar temperature, rate and hardness, as compared to hexavalent chromium. Plating thickness ranges from 5 to 50 μin (0.13 to 1.27 μm). [2]
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).

Chromium compounds are compounds containing the element chromium (Cr). Chromium is a member of group 6 of the transition metals. The +3 and +6 states occur most commonly within chromium compounds, followed by +2; charges of +1, +4 and +5 for chromium are rare, but do nevertheless occasionally exist. [3] [4]
dirubidium chromium sulfate hexahydrate Cs Cr Cs 2 [Cr(H 2 O) 6](SO 4) 2 [23] dicaesium chromium sulfate hexahydrate ND 4: Cr (ND 4) 2 Cr(SO 4) 2 · 6 H 2 O [23] dideuterated ammonium chromium sulfate hexahydrate bright blue, formed from with ammonium sulfate in minimal water under nitrogen gas. Stable in air from oxidation, but may dehydrate.
