Q.42:- Show by a chemical reaction with water that Na20 is a basic oxide and Cl207 is an acidic oxide.
Na2 0reacts with water to form sodium oxide which turns red litmus blue.
Na20 +H20——-> 2NaOH
Therefore, Na20 is a basic oxide
In contrast,Cl207 reacts with water to form perchloric acid which turns blue litmus red.
Therefore, Cl207 is an acidic oxide.
