The oxide ions in a metal oxide generally react with water to form hydroxide ions which are basic in nature (OH-). Here's a complete reaction example :
The oxide ion tends to react with water to form hydroxide ions.
generically O2- + H2O --> 2OH-
As an example, CaO + H2O ---> Ca(OH)2
Some other metal oxides (like ZnO and Al2O3) are basic BUT also acidic oxides:
ZnO + H2O + 2 OH- --> Zn(OH)42- in which reaction hydroxide is needed and NOT formed! This behaviour is usually termed amphoteric.

Is metal oxide is a base?
Yes, certain metal oxides, mostly from the middle groups of the transition metals are acidic. Chromium and rhenium, for example, both form oxides which are acidic in water.
Is barium nitrite basic acidic?
barium oxide is basic oxide.As Barium is a metal so metal forms basic oxide.
Is Cs2O an acid or base?
It is an oxide of alkali metal Cesium, so it is basic in nature,.
Why oxides of magnisium are basic in nature?
There is only one oxide of magnesium, MgO, and it is basic in nature.
Is Rb2O acidic or basic?
It is strongly basic as it is an oxide of an alkali metal.
What is the nature of metal-oxide?
A metallic oxide is basic in nature.
Is metal oxide is a base?

Is barium nitrite basic acidic?
barium oxide is basic oxide.As Barium is a metal so metal forms basic oxide.
Is nitric oxide a basic oxide or an acidic?
Nitric oxide is acidic in nature.
Is strontium oxide a metal?
strontium is alkaline earth metal and its oxide is a basic alkaline.
Is Cs2O an acid or base?
It is an oxide of alkali metal Cesium, so it is basic in nature,.
Why oxides of magnisium are basic in nature?
There is only one oxide of magnesium, MgO, and it is basic in nature.
Is Rb2O acidic or basic?
It is strongly basic as it is an oxide of an alkali metal.
What happens when a metallic oxide dissolves in water?
metallic oxide react with water to form its hydroxides. all these metal oxide are basic in nature due to more electropositive nature of metal atom. EX. M2O + H2O --> 2MaOH The alkali metal oxides M2O (M = Li, Na, K, Rb) Na2O + H2O --> 2NaOH sodium oxide dissolve in water afford sodium hydroxide
What is nature of non metal oxide?
It is electronegetive in nature and so it can be called acidic.
Is potassium oxide is a metal or nonmetal?
No potassium OXIDE is not: IT IS A METAL. IT IS A METAL.And it is not a NONmetal either.Potassium OXIDE K2O is a basic oxide: with water it forms (only) potassium hydroxide, KOHPotassium (elemental) is a alkali metal
What is formed when a metal oxide react with water?
A basic solution
