A large number of chromium(III) compounds are known, such as chromium(III) nitrate, chromium(III) acetate, and chromium(III) oxide. [8] Chromium(III) can be obtained by dissolving elemental chromium in acids like hydrochloric acid or sulfuric acid, but it can also be formed through the reduction of chromium(VI) by cytochrome c7.

Chromium(III) picolinate (also trivalent chromium) is a chemical compound with the formula Cr(C 5 H 4 N(CO 2)) 3, commonly abbreviated as CrPic 3. It is a bright-red coordination compound derived from chromium (III) and picolinic acid .
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+. [11] 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 ...
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 ...
