The chemical formula is Cr(OH)3 and the compound is called chromium hydroxide.
This hydroxide is soluble in water.
Chromium hydroxide is a toxic substance, as many other chromium compounds.

Cr2+, Cr3+ and Cr6+ are the most common ions


The chemical formula of chromium nitrate is Cr(NO3)3.


Chromium (III) nitrate is formed by the reaction between Cr3+ ions and NO3- ions. Thus, forces of attraction due to disparity of charges causes this reaction. As such, we can safely say this is an ionic compound because it is formed by ions.


Cr3+. It's an oxidation of chromium. The anion is hydroxide.


Ruby is α-alumina (the most stable form of Al2O3) in which a small fraction of the Al3+ ions are replaced by Cr3+ ions. Each Cr3+ is surrounded octahedrally by six O2- ions.This crystallographic arrangement strongly affects each Cr3+, resulting in light absorption in the yellow-green region of the spectrum and thus in the red color of the gem (ruby, from Latin ruber means 'red'). When yellow-green light is absorbed by Cr3+, it is re-emitted as red luminescence (the first laser light was made by ruby crystals).


Chromium oxide: 2Cr3+ + 2O2- --> Cr2O3


Chromium III is Cr3+. The roman numeral tells you the charge. Sulfide is S2-. You can figure this out from the periodic table. Sulfur needs two electrons to be like Argon, the next noble gas. When they form a compound, they combine in a ratio such that the total positive charge balances the total negative charge. 2 Cr3+ ions have a total charge of +6. 3 S2- ions have a total charge of -6. So the formula is Cr2S3.


The mmon ions of chromium are Cr3+ and Cr6+; also exist valences 0, 1, 2, 4 and 5.


Not directly. CrCl3 needs to be in a solution with water first. The addition of sodium carbonate will react with the solution forming hydroxide ions, which willreact with the Cr3+ ions in the solution to form a green precipitate, Cr(OH)3. CO3- = CO2 + O2- O2- + H2O = 2 OH- Cr3+ (aq) + 3OH- (aq) = Cr(OH)3


Chromium is a half metal: Cr(III) oxide is basic Cr2O3 forming Cr3+ ions in acid solution. and Cr(VI) oxide is acidic, forming chromate CrO42- and bichromate Cr2O72- ions


What volume of 0.1125 M K2Cr2O7 would be required to oxidize 48.16 mL of 0.1006 M Na2SO3 in acidic solution? The products include Cr3+ and SO42- ions.


The most important cation of chromium is Cr3+; but also exist Cr3+, Cr6+, Cr1+, Cr4+, Cr5+.


Ruby is essentially just the compound aluminum oxide (Al2O3) doped with chromium (which makes it red). The Cr3+ ions occupy only a very small percentage of the Al3+ positions in the crystal lattice, so the molar mass of ruby is essentially the same as aluminum oxide: 2 (26.98) + 3 (16.00) = 101.96 grams / mole



CrI3 contains the Cr3+ cation.



Method:Chromium = Cr3+ + Carbonate = CO3 2-Cr3+ + CO32- = Cr2(CO3)3Note how and where the numbers and compounds are replaced.Sorry I can not explain in full but this is basically how its done.


Chromium II phosphate is Cr3(PO4)2



Longhurst Road Woldingham Caterham CR3 United Kingdom


Chromium's atomic number is 24. A neutral atom of chromium would thus have 24 protons and 24 electrons. Since we're dealing with Cr3+, though, we need to subtract 3 electrons from this number, giving us 21.


A ruby is a pink to blood-red gemstone, a variety of the mineral corundum (aluminium oxide). The red color is caused mainly by the presence of the element chromium.It is not a chemical compound with fixed ratios of elements, it is essentially Al2O3 with some Al3+ replaced by Cr3+
