Question

Classify the following oxides into three types and name the types.
CaO, MgO, CO₂, SO₃, Na₂O, ZnO,Al₂O₃, Fe₂O₃

Answer 1

The given oxide can be classified into three main types.

$\underline{1. Amphoteric Oxide.}$
ZnO (Zinc Oxide.)
Al₂O₃ (Aluminium Oxide.)

$\underline{Amphoteric Oxide.}$ ⇒Amphoteric oxide are those oxides which have both the properties of the acids and bases.

$\underline{Bases}$.
MgO (Magnesium Oxide)
Na₂O(Sodium Hydroxide)
Fe₂O₃(Ferric Oxide)
CaO(Calcium Oxide.)

Bases ⇒Bases are those substances which when disolved in water produces the high concentration of the Hydroxide ions.

$\underline{Acidic Oxide.}$
CO₂ (Carbon dioxide)
SO₃ (Sulphur dioxide)

Acidic oxide ⇒ Acidic oxides are those oxides which have the properties of acids and they are gaseous in nature.



Hope it helps.
