Take oxalate solution in a test tube and heat it strongly. Take a burning match stick at the mouth of test tube and we will see that initially fire becomes strong, but on further heating, gas put off the fire itself. The burned gas is $C O_{2}$ and the CO puts off burning $C O_{2}$ .

Solution

The correct option is B False
When the solution of oxalate ion is heated, CO and carbon dioxide gases are evolved. The molecular weight of CO is lower than that of carbon dioxide. Hence, CO diffuses more rapidly than carbon dioxide.
(a) Hence, the CO gas burns.
(b) When heating is continued, carbon dioxide goes upward. It puts off burning CO.

Hence, the given statement is false.
