Solution

The correct option is C The flame extinguishes and the gas does not bum.
When Ethanoic acid was added to sodium bicarbonate solution and the gas evolved was tested with a burning splinter then the flame extinguishers and the gas does not burn. because When ethanoic acid was added to sodium bicarbonate solution the gas evolved is $c a r b o n d i o x i d e .$
When was produced carbon dioxide is tested by introducing a splinter near to it the gas turns off the flame and it does not burn $as carbon dioxide has a nature to extinguish the fire.$

A student takes about 2mL of ethanoic acid in a dry test tube and adds a pinch of sodium hydrogen carbonate to it. He reports the following observations:

I. Immediately a colorless and odorless gas evolves with brisk effervescence.

II. The gas turns lime water milky when passed through it.

III. The gas bums with an explosion when a burning splinter is brought near it.

IV. The gas extinguishes the burning splinter that is brought near it.
