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.
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 precipitate.
2 O + 3 e − → Cr(OH) 3 + 5 OH − (ε 0 = −0.13 V) Sodium chromate (Na 2 CrO 4) Chromium(VI) compounds in solution can be detected by adding an acidic hydrogen peroxide solution. The unstable dark blue chromium(VI) peroxide (CrO 5) is formed, which can be stabilized as an ether adduct CrO 5 ·OR 2. [6] Chromic acid has the hypothetical ...
The tables below provides information on the variation of solubility of different substances (mostly inorganic compounds) in water with temperature, at one atmosphere pressure. Units of solubility are given in grams of substance per 100 millilitres of water (g/100 ml), unless shown otherwise.
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]
Nitrosyl chloride is produced as a by-product; it bubbles out of the solution as a gas. More conveniently, the salt can be made by reacting nitric acid with aluminium hydroxide . Aluminium nitrate may also be prepared a metathesis reaction between aluminium sulfate and a nitrate salt with a suitable cation such as barium, strontium, calcium ...

The 1:1 complex is tetrahedral in the gas phase, [26] but in the solid phase it is dimeric with bridging hydrogen centres, [(CH 3) 3 NAlH 2 (μ-H)] 2. [27] The 1:2 complex adopts a trigonal bipyramidal structure. [26] Some adducts (e.g. dimethylethylamine alane, (CH 3 CH 2)(CH 3) 2 N·AlH 3) thermally decompose to give aluminium and may have ...
