Answer:
Examples of metallic oxide – CaO, MgO, Fe3O4, BaO, ZnO etc. Basic Oxide – If an oxide reacts with water and forms a base is called basic oxide. Thus, basic oxide on reacting with water gives base. ... It behaves as an acidic oxide and basic oxide both.
Acidic Oxides - If an oxide reacts with water
and forms an acid is called acidic oxide. Thus, acidic oxide on reacting with water gives base. It means if we prepare a solution of acidic oxide and water and dip a blue litmus paper in it then it turns red. Mostly acidic oxides are oxides of non-metals but some oxides of metals with high oxidation states also possess acidic character. Thus, few metallic oxides such as CrO3, Mn₂O, etc. are also acidic oxides.
Examples of acidic oxides - SO2, CO2, SO3 etc.
SO3 + H2O -----> H2SO4
Basic Oxide - If an oxide reacts with water and forms a base is called basic oxide. Thus, basic oxide on reacting with water gives base. It means if we prepare a solution of basic oxide and water and dip a red litmus paper in it then it turns blue.
Examples of basic oxides - MgO, CaO, Bao etc.
Na2O + H2O ------> 2NaOH
