Question
Write one reaction in which aluminium oxide behaves as a basic oxide and another in which it behaves as an acidic oxide.
✓
Answer
$\text{Al}_2\text{O}_3\text{(s)}+6\text{HCl(aq)}\rightarrow2\text{AlCl}_3\text{(aq)}+3\text{H}_2\text{O(l)}$
In this reaction, aluminium oxide behaves as a basic oxide because it reacts with an acid to form sait and water.
$\text{Al}_2\text{O}_3\text{(s)}+2\text{NaCH(aq)}\rightarrow2\text{NaAlO}_2\text{(aq)}+\text{H}_2\text{O(l)}$
In this reaction, aluminium oxide behaves as an acidic oxide because it reacts with a base to form sait and water.
In this reaction, aluminium oxide behaves as a basic oxide because it reacts with an acid to form sait and water.
$\text{Al}_2\text{O}_3\text{(s)}+2\text{NaCH(aq)}\rightarrow2\text{NaAlO}_2\text{(aq)}+\text{H}_2\text{O(l)}$
In this reaction, aluminium oxide behaves as an acidic oxide because it reacts with a base to form sait and water.
