Chromium(III) chloride (also called chromic chloride) is an inorganic chemical compound with the chemical formula Cr Cl 3.It forms several hydrates with the formula CrCl 3 ·nH 2 O, among which are hydrates where n can be 5 (chromium(III) chloride pentahydrate CrCl 3 ·5H 2 O) or 6 (chromium(III) chloride hexahydrate CrCl 3 ·6H 2 O).
Chromium (II) chloride describes inorganic compounds with the formula Cr Cl 2 (H 2 O) n. The anhydrous solid is white when pure, however commercial samples are often grey or green; it is hygroscopic and readily dissolves in water to give bright blue air-sensitive solutions of the tetrahydrate Cr (H 2 O) 4 Cl 2.
Chromium compounds. 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 ...
This kind of chromic acid may be used as a cleaning mixture for glass. Chromic acid may also refer to the molecular species, H2CrO4 of which the trioxide is the anhydride. Chromic acid features chromium in an oxidation state of +6 (and a valence of VI or 6). It is a strong and corrosive oxidising agent and a moderate carcinogen.
Chromium (III) nitrate describes several inorganic compounds consisting of chromium, nitrate and varying amounts of water. Most common is the dark violet hygroscopic solid. An anhydrous green form is also known. Chromium (III) nitrate compounds are of a limited commercial importance, finding some applications in the dyeing industry. [2]
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. It is obtained by heating the 18-hydrate material above 70 °C. Further heating yields the anhydrous sulfate. A variety of other chromium (III) sulfates are known, but also contain hydroxide or oxide ligands.
Chromium (III) picolinate is a chemical compound with the formula Cr (C 5 H 4 N (CO 2 H)) 3, commonly abbreviated as CrPic 3. It is sold as a nutritional supplement to treat type 2 diabetes and promote weight loss. [ 1 ] This bright-red coordination compound is derived from chromium (III) and picolinic acid.
Anhydrous chromium(III) chloride (CrCl 3) A large number of chromium(III) compounds are known, such as chromium(III) nitrate, chromium(III) acetate, and chromium(III) oxide. [30] 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 ...
