Question

Predict the behaviour of both oxides $N{a}_{2}O$ and $C{l}_2{O}_7$

• A. Both are acidic oxides
• B. Both are basic oxides
• C. $N{a}_{2}O$ is acidic and $C{l}_2{O}_7$ is basic oxide
• D. $N{a}_{2}O$ is basic and $C{l}_2{O}_7$ is acidic oxide

Answer 1

The correct option is D $N{a}_{2}O$ is basic and $C{l}_2{O}_7$ is acidic oxide

Metallic oxides are basic in nature and and non metal oxides are acidic in nature.
$N{a}_{2}O$ is a metallic oxide and $C{l}_2{O}_7$ is a non metallic oxide.

$N{a}_{2}O$ forms a strong base with water whereas $C{l}_2{O}_7$ forms a strong acid with water.So $N{a}_{2}O$ is basic in nature and $C{l}_2{O}_7$ is acidic in nature.
$N{a}_{2}O+H_{2}O\to 2NaOH$ (strong base)
$C{l}_2{O}_7+H_{2}O\to 2HCl{O}_4$ (strong acid)
