Question

A gas is evolved when Ethanol reacts with Sodium. Name the gas evolved and also write the balanced chemical equation of the reaction involved?

Answer 1

The gas evolved when Ethanol reacted with Sodium:

• Ethanol is an Alcohol having a molecular formula, ${\mathrm{C}}_2{\mathrm{H}}_5\mathrm{OH}$.
• It basically reacts with Sodium metals to form sodium alkoxide and Hydrogen gas gets evolved during the process.

The balanced chemical equation of the reaction:

• Ethanol reacts with Sodium metal to form Sodium ethoxide along with the evolution of hydrogen gas.
• The balanced chemical equation of the given reaction can be written as:

$\underset{\left(\mathrm{Ethanol}\right)}{2{\mathrm{C}}_2{\mathrm{H}}_5\mathrm{OH}\left(\mathrm{aq}\right)}+\underset{\left(\mathrm{Sodium}\right)}{2\mathrm{Na}\left(\mathrm{s}\right)}\to \underset{\left(\mathrm{Sodium}\mathrm{ethoxide}\right)}{2{\mathrm{C}}_2{\mathrm{H}}_5\mathrm{ONa}\left(\mathrm{aq}\right)}+{\mathrm{H}}_2\left(\mathrm{g}\right)$
Hence, the gas evolved when Ethanol reacted with Sodium is Hydrogen gas, for which the balanced reaction has been given above.
