Chromium(II) acetate hydrate, also known as chromous acetate, is the coordination compound with the formula Cr 2 (CH 3 CO 2) 4 (H 2 O) 2. ... The synthesis of Cr 2 ...
Chromium(II) carbide is a ceramic compound that exists in several chemical compositions: ... Synthesis of chromium carbide can be achieved through mechanical alloying.
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(II) carbide (Cr 3 C 2) Chromium(II) compounds are uncommon, in part because they readily oxidize to chromium(III) derivatives in air. Water-stable chromium(II) chloride CrCl 2 that can be made by reducing chromium(III) chloride with zinc. The resulting bright blue solution created from dissolving chromium(II) chloride is stable at ...
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 and +5 for chromium ...
Chromium(II) acetylacetonate is the coordination compound with the formula Cr(O 2 C 5 H 7) 2. It is the homoleptic acetylacetonate complex of chromium(II). It is an air-sensitive, paramagnetic yellow brown solid. According to X-ray crystallography, the Cr center is square planar. [1]
Chromium(II) sulfide may be formed by reaction of chromium metal with sulfur or hydrogen sulfide at high temperature. It may also be formed by reacting chromium(III) chloride with H 2 S, reducing chromium(III) sulfide with hydrogen, or by double replacement reaction of lithium sulfide with chromium(II) chloride. [5] Cr + S → CrS Cr + H 2 S ...
