Chromium(III) hydroxide is a gelatinous green inorganic compound with the chemical formula Cr(OH) 3. It is a polymer with an undefined structure and low solubility. It is amphoteric, dissolving in both strong alkalis and strong acids. [2] In alkali: Cr(OH) 3 + OH − → CrO − 2 + 2 H 2 O In acid: Cr(OH) 3 (OH 2) 3 + 3 H + → Cr(OH 2) 6 3+

Chromium(III) acetate, commonly known as basic chromium acetate, [2] describes a family of salts where the cation has the formula [Cr 3 O(O 2 CCH 3) 6 (OH 2) 3] +. The trichromium cation is encountered with a variety of anions, such as chloride and nitrate. Data in the table above are for the chloride hexahydrate, [Cr 3 O(O 2 CCH 3) 6 (OH 2) 3 ...
Commonly three electrons are added to a chromium atom, reducing it to oxidation state +3. In acid solution the aquated Cr 3+ ion is produced. Cr 2 O 2− 7 + 14 H + + 6 e − → 2 Cr 3+ + 7 H 2 O ε 0 = 1.33 V. In alkaline solution chromium(III) hydroxide is produced.
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 of crystallization. Hydrated 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.
