Question

How does baking soda and vinegar react with each other?
A. Undergoes acid-base reaction
B. Exchange atoms
C. Both (A) and (B)
D. High temperature

Answer 1

Hint: Here you should know that Baking soda is sodium bicarbonate ($NaHCO_{ 3 }$) and vinegar is acetic acid ($CH_{ 3 }COOH$). One of the products of this reaction is carbon dioxide. Now try to answer this accordingly.

Complete step by step answer:
As we already know Baking soda is sodium bicarbonate and Vinegar contains acetic acid.
When both of them are combined, the hydrogen atom in the acetic acid meets up with the hydrogen and oxygen atoms in the baking soda (base) to form a molecule of water, while the acetate ion grabs onto the sodium atom and forms a salt, sodium acetate.
The carbon dioxide molecule, free of its other chemical bonds, can now escape and bubbles forth as a gas.
The chemical equation for the overall reaction is:
$NaHCO_{ 3 }(s)\quad +\quad CH_{ 3 }COOH(l)\quad \rightarrow \quad CO_{ 2 }(g)\quad +\quad H_{ 2 }O(l)\quad +\quad Na^{ + }(aq)\quad +\quad CH_{ 3 }COO^{ - }(aq)$

This chemical reaction is an acid-base reaction. We know that in a chemical reaction there is always an exchange of atoms.
Therefore, we can conclude that the correct answer to this question is option C.

Note: The carbon dioxide released by the baking soda and vinegar reaction has other uses besides making a chemical volcano. It can be collected and used as a simple chemical fire extinguisher. Because carbon dioxide is heavier than air, it displaces it. This starves a fire of the oxygen needed for combustion.
