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 · n H 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 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 ...
The following chart shows the solubility of various ionic compounds in water at 1 atm pressure and room temperature (approx. 25 °C, 298.15 K). "Soluble" means the ionic compound doesn't precipitate, while "slightly soluble" and "insoluble" mean that a solid will precipitate; "slightly soluble" compounds like calcium sulfate may require heat to ...

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 (III) hydroxide (Cr (OH) 3) is amphoteric, dissolving in acidic solutions to form [Cr (H 2 O) 6] 3+, and in basic solutions to form [Cr (OH)6]3−. It is dehydrated by heating to form the green chromium (III) oxide (Cr 2 O 3), a stable oxide with a crystal structure identical to that of corundum.
Chromium (II) chloride is used as precursor to other inorganic and organometallic chromium complexes. Alkyl halides and nitroaromatics are reduced by CrCl 2. The moderate electronegativity of chromium and the range of substrates that CrCl 2 can accommodate make organochromium reagents very synthetically versatile. [9]
Potassium dichromate is an oxidising agent in organic chemistry, and is milder than potassium permanganate. It is used to oxidize alcohols. It converts primary alcohols into aldehydes and, under more forcing conditions, into carboxylic acids. In contrast, potassium permanganate tends to give carboxylic acids as the sole products.
