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.
