Question

On adding acetic acid to sodium hydrogen carbonate in a test tube, a student observes; A. no reaction; B. a colorless gas with pungent smell .; C. bubbles of a colorless and odourless gas; D. a strong smell of vinegar(All India - 2012)

Answer 1

Answer:

Answer is C- bubbles of colourless and odourless gas

Answer 2

On adding acetic acid to sodium hydrogen carbonate in a test tube, a student observes the evolution of bubbles of a colorless and odorless gas.

Explanation:

• The chemical equation involved in the reaction of acetic acid with sodium hydrogen carbonate is as follows:

$NaHCO_3+CH_3COOH\rightarrow CH_3COONa+H_2O+CO_2$

• As per the above chemical equation, it is clear that carbon dioxide is obtained as one of the products.
• Due to the formation of carbon dioxide bubbles of a colorless and odorless gas evolves.
• Thus the students observe the observation given in option C.
