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.
The Pourbaix diagram for chromium in pure water, perchloric acid, or sodium hydroxide [1] [2] 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 ...
Chromium(II) carbide (Cr 3 C 2) Chromium(II) compounds are uncommon, in part because they readily oxidize to chromium(III) derivatives in air. Water-stable chromium(II) chloride CrCl 2 that can be made by reducing chromium(III) chloride with zinc. The resulting bright blue solution created from dissolving chromium(II) chloride is stable at ...
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]

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.
Chromium(III) sulfate usually refers to the inorganic compounds with the formula Cr 2 (SO 4) 3. x(H 2 O), where x can range from 0 to 18. Additionally, ill-defined but commercially important "basic chromium sulfates" are known. These salts are usually either violet or green solids that are soluble in water. It is commonly used in tanning leather.
