Question

How many of the following oxides are basic oxides?

$C O_{2}, S n O_{2}, P b O, P b O_{2}, P b_{3} O_{4}, A l_{2} O_{3}$

Open in App

Solution

$C O_{2}$ and $S n O_{2}$ are acidic oxides.
$P b O$ and $A l_{2} O_{3}$ are amphoteric oxides. it can act as a base or acid.
$P b O_{2}$ and $P b_{3} O_{4}$ are basic oxides.
Thus, two oxides are basic oxides.
