Show by a chemical reaction with water that Na2O is a basic oxide and C12O7 is an acidic oxide.
Na2O reacts with water to form a strong base whereas C12O7 forms a strong acid. Na2O + H2O → 2NaOH (strong base) C12O7 + H2O → 2HClO4 (strong acid) , Their basic or acidic nature can be qualitatively tested with litmus paper.
