Final answer:
In chemistry, oxides can be classified as acidic, basic, amphoteric, or neutral. Acidic oxides produce acidic solutions or are soluble in aqueous base. Basic oxides produce basic solutions or dissolve in aqueous acid. Amphoteric oxides can dissolve in both acidic and basic solutions. Neutral oxides do not produce acidic or basic solutions.
Step-by-step explanation:
Acidic oxides: CO2, NO2, Al2O3, SO3
Basic oxides: CaO, CO, SO3, K2O, BaO
Amphoteric oxides: Al2O3, CaO, SnO2
Neutral oxides: NO, SnO2, N2O5, BaO
Acidic oxides are oxides of nonmetallic elements that produce an acidic solution when reacted with water or are soluble in aqueous base. Basic oxides are oxides of metallic elements that produce a basic solution when reacted with water or dissolve in aqueous acid. Amphoteric oxides are oxides that can dissolve in both acidic and basic solutions. Neutral oxides are oxides that neither produce an acidic nor a basic solution when reacted with water or other solutions.
