Question

Which of the set of oxides are arranged in the proper order of basic, amphoteric, acidic ? (A) SO2, P2O5, CO  (B) BaO, Al2O3, SO2  (C) CaO, SiO2, Al2O3  (D) CO2, Al2O3, CO

Tardigrade Admin · Accepted Answer

The correct set of oxides arranged in the proper order of basic, amphoteric, acidic are

B a O, A l_{2} O_{3}, S O_{2}

Oxides of non-metallic elements are acidic such as

C O_{2}, N O_{2}, S O_{2}

etc. Oxides of less electropositive elements (such as

B e O, A l_{2} O_{3}, B i_{2} O_{3}, Z n O

etc. ) are amphoteric i.e. these behaves as acids toward strong bases and as bases towards strong acids. Oxides of electropositive elements

(N a_{2} O, C a O, Tl l_{2} O, B a O

etc.) are basic and contain discrete

O^{2 -}

ions.
