What ions are present in chromium III oxide?
Chromium oxide is the light green inorganic compound coCr203. When dissolved in acid, it produces the hydrated chromium ions [Cr(H2O)6]3+.
What is the formula of Chromium (II) oxide?
The formula of Chromium (II) oxide is CrO.
What happens when HNO2 undergoes disproportionation?
When HNO2 undergoes disproportionation, it can transform into different products depending on the conditions. In acidic solution, it can form nitric oxide (NO) and nitrous acid (HNO3). In basic solution, it can produce salt of nitrite ion (NO2-) and salt of nitrate ion (NO3-).
Is chromium a metal?
Chromium is the hardest metal; Mohs hardness of chromium is 8,5.
What is the name Cr2O5?
Cr2O3 is usually considered to be an ionic compound, in which instance its proper name is "chromium (III) oxide" (now preferred) or "chromic oxide" (more often used about 50 years ago.) If Cr2O3 is considered to be covalently bonded, its proper systematic name would be "dichromium trioxide." Some chemists also call it "chromic acid anhydride."

Can you make chromium III sulfate from chromium III oxide?
Yes, chromium(III) sulfate can be made by reacting chromium(III) oxide with sulfuric acid. The chemical equation is: Cr2O3 + 3H2SO4 → Cr2(SO4)3 + 3H2O. The resulting compound is chromium(III) sulfate with the formula Cr2(SO4)3.
What is the correct compound for Cr2O3?
The compound Cr2O3 is chromium(III) oxide. It is a naturally inorganic occurring compound and it is used primarily as green pigment.
What is the formula of Chromium (II) oxide?
The formula of Chromium (II) oxide is CrO.
What is the composition of chromium oxide and aluminium oxide in ruby?
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.
What is the name for the compound with the formula Cr2O3?
Cr2O3 is, Chromium (III) oxide or simply Chromium oxide.
What is the formula for chromium III oxide?
Chromium oxide may refer to:Chromium(II) oxide, CrOChromium(III) oxide, Cr2O3Chromium dioxide (chromium(IV) oxide), CrO2Chromium trioxide (chromium(VI) oxide), CrO3

What is a Cannizzaro reaction?
A Cannizzaro reaction is the disproportionation of an aldehyde into an alcohol and carboxylic acid.
Is chromium a metal?
Chromium is the hardest metal; Mohs hardness of chromium is 8,5.
Chromium IV oxide formula?
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>
