Question

A student takes Na2CO3 powder in a test tube and pours some drops of acetic acid over it. He observes:(A) no reaction in the test tube(B) colourless gas with pungent smell(C) bubbles of a colourless and odourless gas(D) white fumes with smell of vinegar

Answer 1

I think option B will be the right answer as when this reaction arises then it will form
CH3COOH+NA2CO3=CH3COONA+CO2

Answer 2

According to the data mentioned in the question,

A student takes Na2CO3 powder in a test tube and pours some drops of acetic acid over it. He observes:

The correct answer of this question is option C,"bubbles of a colourless and odourless gas."

In this chemical reaction,the colourless and the odurless gas bubbles are actually the generated carbon dioxide gas.
