A student takes 2 mL acetic acid in a dry test tube and adds a pinch of sodium hydrogen carbonate to it. He makes the following observations
I. A colorless and odourless gas evolves with a brisk effervescence.
II. The gas turns lime water milky when passed through it.
III. The gas burns with an explosion when a burning splinter is brought near it.
The gas extinguishes the burning splinter that is brought near it.

The correct option is D IV,
I and II
When 2 mL acetic acid is taken in a dry test tube and a pinch of sodium hydrogen carbonate is added to it, a colourless and odourless gas evolves with a brisk effervescence which is CO2.
When CO2. is passed through lime water it turms lime water milky
CO2. also extinguishes th eburning splinter when it is brought near it.
