Ethanol reacts with sodium and forms two products which are?

When ethanol reacts with sodium, it leads to the formation of two products: hydrogen gas and a compound known as sodium ethoxide. Sodium is a highly reactive metal that is typically stored in kerosene to prevent unwanted reactions with moisture or air.

Chemical Reaction

The reaction can be represented as follows:

2Na + 2CH₃CH₂OH → 2CH₃CH₂O^-Na⁺ + H₂ Ethanol + Sodium metal → Sodium ethoxide + Hydrogen gas    

Here, ethanol reacts with sodium, replacing one hydrogen atom in the ethanol molecule to form sodium ethoxide. Simultaneously, hydrogen gas is released during the reaction.

Testing the Reaction

To confirm the presence of hydrogen gas, bring a burning matchstick near the gas evolved during the reaction. Hydrogen gas will burn with a characteristic 'pop' sound, indicating its presence. This test is a simple and effective method to demonstrate that ethanol reacts with sodium to produce hydrogen gas.

Applications of the Reaction

• Sodium ethoxide is an important compound used in organic synthesis, including the production of biofuels and other chemicals.
• Understanding how ethanol reacts with sodium is essential for laboratory and industrial applications in chemical research.
