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 CrCl3·nH2O, among which are hydrates where n can be 5 (chromium (III) chloride pentahydrate CrCl3·5H2O) or 6 (chromium (III) chloride hexahydrate CrCl3·6H2O).
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 ...
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.
Infobox references. 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 ...
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 ...
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.
Chromium trioxide (also known as chromium (VI) oxide or chromic anhydride) is an inorganic compound with the formula CrO3. It is the acidic anhydride of chromic acid, and is sometimes marketed under the same name. [6] This compound is a dark-purple solid under anhydrous conditions and bright orange when wet.
Sodium chromate is the inorganic compound with the formula Na 2 CrO 4. It exists as a yellow hygroscopic solid, which can form tetra-, hexa-, and deca hydrates. It is an intermediate in the extraction of chromium from its ores.
