Question

)Identify the following oxides with neutral, acidic, basic and amphoteric oxidesAl2O3 ii) MgO iii) SO2 iv) CO v) Na2O vi) N2O vii) ZnO viii) CO2 ix) SO3 x) CaO.

Answer 1

Answer:

Amphoteric oxides - i) Al2O3, vii) ZnO

Basic oxides - ii) MgO, v) Na2O, x) CaO

Acidic oxides - iii) SO2, iv) Co, viii) CO2, ix) SO3

Neutral oxides - vi) N2O

Answer 2

Amphoteric:

$Al_2O_3, ZnO$

Basic: Na2O,MgO, CaO

Acidic: SO2, CO, SO3

Neutral : N2O

• The oxides which can act as both acid and base are called amphoteric oxide.
• The oxides which can act as a acid are called acidic oxides.
• The oxides which are basic in nature are called basic oxides.
• The oxides which are neither acid nor base are called neutral oxides.
