Chromium(II) bromide is the inorganic compound with the chemical formula CrBr 2. Like many metal dihalides, CrBr 2 adopts the "cadmium iodide structure" motif, i.e., it features sheets of octahedral Cr(II) centers interconnected by bridging bromide ligands. It is a white solid that dissolves in water to give blue solutions that are readily ...
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 and +5 for chromium are rare, but do nevertheless occasionally exist.
Aluminium carbonate (Al 2 (CO 3) 3), is a carbonate of aluminium.It is not well characterized; one authority says that simple carbonates of aluminium are not known. [2] However related compounds are known, such as the basic sodium aluminium carbonate mineral dawsonite (NaAlCO 3 (OH) 2) and hydrated basic aluminium carbonate minerals scarbroite (Al 5 (CO 3)(OH) 13 •5(H 2 O)) and ...
Under the generic name "algeldrate", aluminium hydroxide is used as an antacid in humans and animals (mainly cats and dogs). It is preferred over other alternatives such as sodium bicarbonate because Al(OH) 3, being insoluble, does not increase the pH of stomach above 7, and hence does not trigger secretion of excess acid by the stomach. Brand ...
Analogous to the behavior of related chromium(III) halides, the tribromide dissolves in water to give CrBr 3 (H 2 O) 3 only upon the addition of catalytic amounts of a reducing agent, which generates CrBr 2. [1] The reducing agent generates chromous bromide on the surface of the solid, which dissolves and re-oxidizes to Cr(III). [citation needed]
Chromium(III) boride, also known as chromium monoboride (CrB), is an inorganic compound with the chemical formula CrB. [2] It is one of the six stable binary borides of chromium, which also include Cr 2 B, Cr 5 B 3, Cr 3 B 4, CrB 2, and CrB 4. [3]
The tetrahydrate has been obtained by crystallization of the dibromide from aqueous solution. At 3.04 g/cm 3, it is much less dense than the anhydrous material. According to X-ray crystallography, the tetrahydrate is a polymer of CdBr 2 (H 2 O) 2 with bridging bromide ligands. There are two interstitial water molecules [3]
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+
