Q. Show the broader classification?

A broader classification is based on the reaction of the oxide with water. According to this, oxides are classified as' acidic, basic, neutral or amphoteric.

Acidic oxides dissolve in water to give acidic solutions. These react with alkalis forming a salt and water, e.g., CO₂ NO2, SO₂, etc.

Co₂ + H₂O-----------------> H₂CO₃

CO₂+ 2NaOH---------------------> Na₂CO₃ + H₂

Basic oxides dissolve in water to give alkaline solutions. These react with acids forming salt and water, e.g., Na₂O, CaO, MgO, etc.
