Which is the correct formula for titanium III oxide?

Ti2O3Titanium(III) oxide/Formula

Is zno amphoteric?

An amphoteric oxide is one that can act as a base or as an acid. … This oxide reacts with base and acid to produce salt and water as the main products. Amphoteric oxides react with both acids and alkalis to form salt and water. Examples of amphoteric oxides are zinc oxide and aluminum oxide.

Which oxide is most basic?

Na2O is the most basic oxide.Al2O3 is amphoteric.P2O5 is acidic oxide.SiO2 is weakly acidic oxide. Hence, the option (D) is correct answer.

Is Cr2O3 amphoteric oxide?

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−.

What type of bond is Cr2O3?

ionic bondThe name of Cr2 O3 is chromium (III) oxide. Cr2 O3 is an ionic bond, so the name of the first atom is just the elemental name.

What is the oxidation state of Cr2O3?

+3Another significant oxygen compound is chromium oxide, also known as chromium sesquioxide or chromic oxide, Cr2O3, in which chromium is in the +3 oxidation state. It is prepared by calcining sodium dichromate in the presence of carbon or sulfur.

Is CrO acidic or basic?

state) \ CrO is basic, CrO3 is acidic and Cr2O3 is amphoteric.

Which oxide of chromium is more acidic?

Is cro3 acidic or basic?

Chromium trioxide (also known as chromium(VI) oxide or chromic anhydride) is an inorganic compound with the formula CrO3. It is the acidic anhydride of chromic acid, and is sometimes marketed under the same name.

Is cro3 amphoteric?

-In V2O4, the oxidation state of vanadium is +4 which shows that it tends to donate a pair of the electron that’s why it is as basic only and not amphoteric.

Is sno2 amphoteric?

Although SnO2 is insoluble in water, it is amphoteric, dissolving in base and acid.

What gives the least basic oxide?

Lithium monoxide (Li2O) is least basic. On moving down the group in alkali metals, the baicity of oxides increases.

Is cl2o acidic or basic?

It will give an acidic solution. Hints: is Dichlorine monoxide. It’s a brownish-yellow gas at room temperature; it is highly soluble in both water and organic solvents. , while dissolved in water exists in equilibrium with , though, the equilibrium constant favors the formation of .

Is al2o3 acidic oxide?

Aluminum Oxide Aluminium oxide is amphoteric. It has reactions as both a base and an acid. Reaction with water: Aluminum oxide is insoluble in water and does not react like sodium oxide and magnesium oxide. The oxide ions are held too strongly in the solid lattice to react with the water.

What Cr2O3 called?

Chromium(III) oxide.

Is Cr2O3 ionic?

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

Why is Cr2O3 amphoteric?

In other words, it has less electrons available in its valence shell and is electron deficient. There is also a high effective nuclear charge. As a result, it can accept electrons and behave as an acid. Since in Cr2O3 chromium is in higher oxidation state than in CrO, therefore it is amphoteric while Cro is basic.
