Chromium oxide (Cr₂O₃) is generally considered to be neutral and does not have a specific pH value in its solid form. When chromium oxide is dissolved in water, it does not significantly affect the pH of the solution, typically remaining around neutral (pH 7). However, the exact pH can vary depending on the concentration and presence of other substances in the solution.
The compound Cr2O3 is chromium(III) oxide. It is a naturally inorganic occurring compound and it is used primarily as green pigment.
Ruby is composed primarily of aluminum oxide (Al2O3) with trace amounts of chromium oxide (Cr2O3). The chromium impurities within the aluminum oxide lattice are responsible for the vibrant red color of ruby.
Cr2O3 is, Chromium (III) oxide or simply Chromium oxide.
Chromium oxide may refer to:Chromium(II) oxide, CrOChromium(III) oxide, Cr2O3Chromium dioxide (chromium(IV) oxide), CrO2Chromium trioxide (chromium(VI) oxide), CrO3
CrO2this is the incorrect formula. For Chromium II oxide the formula is actually CrO without the 2. The reason for this is simple. the II after chromium indicates that it has a charge of +2, and the oxygen, we know is in group 16, has a charge of -2. The formula CrO2 is actually the formula for chromium IV oxide>

Chromium
In chromium(III) oxide (Cr₂O₃), the ions present are chromium ions (Cr³⁺) and oxide ions (O²⁻). Each chromium ion carries a +3 charge, while each oxide ion carries a -2 charge. The compound is neutral overall, with two chromium ions balancing out the three oxide ions. Thus, the formula reflects a ratio of 2:3 between chromium and oxide ions.
