Best answer

Such oxides which react both with acids as well as bases to form salts and water are known as Amphoteric Oxides.

For Example — aluminium oxide and zinc oxide.

$\begin{array}{l}\mathrm{ZnO}+2 \mathrm{HCl} \longrightarrow \mathrm{ZnCl}_2+\mathrm{H}_2 \mathrm{O} \\\mathrm{ZnO}+2 \mathrm{NaOH} \longrightarrow \mathrm{Na}_2 \mathrm{ZnO}_2+\mathrm{H}_2 \mathrm{O}\end{array}$
