Question

Choose the correct word from the bracket and fill in the blanks.

When Acetic acid reacts with Sodium, it liberates _________ gas. (Hydrogen/ Oxygen)

Answer 1

1. Ethanoic acid is commonly known as Acetic acid.
2. When Acetic acid reacts with Sodium it forms Sodium acetate and Hydrogen.
3. The chemical reaction is shown below.
   $\underset{(\mathrm{Acetic}\mathrm{acid})}{2{\mathrm{CH}}_3\mathrm{COOH}\left(\mathrm{l}\right)}+\underset{\left(\mathrm{Sodium}\right)}{2\mathrm{Na}\left(\mathrm{s}\right)}\to \underset{(\mathrm{Sodium}\mathrm{acetate})}{2{\mathrm{CH}}_3\mathrm{COONa}\left(\mathrm{s}\right)}+\underset{\left(\mathrm{Hydrogen}\right)}{{\mathrm{H}}_2\left(\mathrm{g}\right)}$
4. The product formed is Sodium acetate salt.
5. Therefore, when Acetic acid reacts with Sodium, it liberates Hydrogen gas.
