What is the formula for Cr2O3?

Cr2O3Chromium(III) oxide / Formula

Is Cr2O3 molecular or ionic?

Answer and Explanation: Cr2 O3 is named chromium (III) oxide. Chromium is a metal and oxygen is a nonmetal, so this is an ionic compound.

What is the nature of Cr2O3?

Chemical Nature of Cr2O3 Chromium has three different oxides. CrO has an oxidation number +2, and is a basic oxide, while CrO3 is acidic with a +6 oxidation number. Cr2O3 is amphoteric. Even if it is insoluble in water, it dissolves in acid to give hydrated chromium ions [Cr(H2O)6]3+.

What are the ions composing cro3?

Chromium trioxide is a chromium oxide composed of a single chromium bound (oxidation state +6) to three oxygens; the acidic anhydride of chromic acid. Chromium trioxide, anhydrous appears as a dark purplish red solid.

What is the charge of chromium in cro3?

…is chromium oxide, commonly called chromium trioxide or chromic acid, CrO3, in which chromium is in the +6 oxidation state.

What is the compound for cro3?

CrO3Chromium trioxide / Formula
chromium compounds …is chromium oxide, commonly called chromium trioxide or chromic acid, CrO3, in which chromium is in the +6 oxidation state.

Is cro3 covalent or ionic?

covalent
Cation in high oxidation state are said to exhibit high polarisibility. Hence, CrO​3 is covalent while CrO is ionic.

What type of oxide is Cr2O3?

Chromium(III) oxide

Is Cr2O3 basic?

Chromium(III) oxide is amphoteric. Although insoluble in water, it dissolves in acid to produce hydrated chromium ions, [Cr(H2O)6]3+ which react with base to give salts of [Cr(OH)6]3−.
