Question

The gas released on mixing baking soda with vinegar.

Answer 1

Baking soda, commonly known as sodium hydrogen carbonate, is a white crystalline substance. In water, it is just slightly soluble. Vinegar, which is commonly known as acetic acid, is a kind of acid.

• When baking soda $\left({\mathrm{NaHCO}}_3\right)$ reacts with vinegar $\left({\mathrm{CH}}_3\mathrm{COOH}\right)$ it released carbon dioxide$\left({\mathrm{CO}}_2\right)$.
• The chemical equation is as follows:

$\underset{\mathrm{Baking}\mathrm{soda}}{{\mathrm{NaHCO}}_3\left(\mathrm{g}\right)}+\underset{\mathrm{Vinegar}}{{\mathrm{CH}}_3\mathrm{COOH}\left(\mathrm{l}\right)}\to \underset{\mathrm{Carbon}\mathrm{dioxide}}{{\mathrm{CO}}_2\left(\mathrm{g}\right)}+\underset{\mathrm{Water}}{{\mathrm{H}}_2\mathrm{O}\left(\mathrm{l}\right)}+{\mathrm{CH}}_3{\mathrm{COO}}^{-}\left(\mathrm{aq}\right)+{\mathrm{Na}}^{+}\left(\mathrm{aq}\right)$

So, Carbon dioxide gas is released by mixing baking soda with vinegar.
