Commercially available chromium(III) chloride hydrate is the dark green complex [CrCl 2 (H 2 O) 4]Cl. Closely related compounds are the pale green [CrCl(H 2 O) 5 ]Cl 2 and violet [Cr(H 2 O) 6 ]Cl 3 . If anhydrous violet [ 10 ] chromium(III) chloride is dissolved in water, the violet solution turns green after some time as the chloride in the ...
This can only be used as a very rough guide, for instance if a narrow range of wavelengths within the band 647–700 nm is absorbed, then the blue and green receptors will be fully stimulated, making cyan, and the red receptor will be partially stimulated, diluting the cyan to a greyish hue.
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 ·nH 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).

A 2.26 kΩ, 1%-precision resistor with 5 color bands (), from top, 2-2-6-1-1; the last two brown bands indicate the multiplier (×10) and the tolerance (1%).. An electronic color code or electronic colour code (see spelling differences) is used to indicate the values or ratings of electronic components, usually for resistors, but also for capacitors, inductors, diodes and others.
It is used in paints, inks, and glasses. It is the colorant in "chrome green" and "institutional green." Chromium(III) oxide is a precursor to the magnetic pigment chromium dioxide, by the following reaction: [8] Cr 2 O 3 + 3 CrO 3 → 5 CrO 2 + O 2
Most common is the dark violet hygroscopic solid. An anhydrous green form is also known. Chromium(III) nitrate compounds are of a limited commercial importance, finding some applications in the dyeing industry. [2] It is common in academic laboratories for the synthesis of chromium coordination complexes.
