Question

Why metallic oxides are basic in nature whereas non-metallic oxides are acidic in nature ?

Answer 1

Answer:

Metallic oxides are basic in nature because they react with dilute acids to form salt and water. They also react with water to form metal hydroxides which are alkaline in nature because these metal hydroxides release OH- ions in solution. ... Therefore, non metallic oxides would be acidic in nature.

Answer 2

Metal oxides dissolve in water to give basic substances nonmetallic substances dissolve in water to give acidic substances. So metallic oxides are basic in nature whereas non-metallic oxides are acidic in nature

when a metal reacts with oxygen it gives metal oxides.

Example: MgO, BaOMetal oxides react with water to give basic substances.MgO and BaO when dissolved with water give Magnesium hydroxide and Barium hydroxide respectively.These hydroxides are basic.The nonmetal reacts with oxygen to give nonmetallic oxides.Example: CO₂, SO₂CO₂ dissolves in water to give carbonic acid.Also, nonmetallic oxides react with the base to give salt and water.Metallic oxides react with acids to give salt and water.These are similar to neutralization reactions.We know,The acid reacts with the base to give salt and water.From this evidence, we can conclude that metallic oxides are basic whereas non-metallic oxides are acidic.
