Question

What happens when a few drops of a saturated solution of Sodium bicarbonate are added to a small quantity of Ethanoic acid?

Answer 1

1. The reaction of organic acid with Sodium bicarbonate gives brisk effervescence of Carbon dioxide gas.
2. When a few drops of saturated solution of Sodium bicarbonate are added to a Ethanoic acid, Sodium acetate, Carbon dioxide and water is produce.
3. The chemical reaction is,

$$\begin{gathered} {\mathrm{CH}}_3\mathrm{COOH}\left(\mathrm{l}\right)+{\mathrm{NaHCO}}_3\left(\mathrm{s}\right)\to {\mathrm{CH}}_3\mathrm{COONa}\left(\mathrm{s}\right)+{\mathrm{CO}}_2\left(\mathrm{g}\right)+{\mathrm{H}}_2\mathrm{O}\left(\mathrm{l}\right) \\ \mathrm{Acetic}\mathrm{acid}\mathrm{Sodium}\mathrm{Sodium}\mathrm{acetate} \\ \mathrm{bicarbonate} \end{gathered}$$
