1.	Show by a chemical reaction with water that Na_(2) Ois a basic oxide and Cl_(2)O_(7)is an acidic oxide.
Answer» SOLUTION :`Na_(2)O` with water forms a strong base whereas `Cl_(2)O_(7)` forms strong acid. `Na_(2) O + H_(2) O to NaOH` `Cl_(2)O_(7) ` REACT with `H_(2)O` and forms strong acid `HClO_(4)`. `Cl_(2)O_(7) + H_(2)I to 2HClO_(4)` ` :. Cl_(2) O_(7)` is an acidic oxide. Their BASIC or acidic nature can be qualitatively tested with litmus paper.
