* Highly Reactive: Sodium is a highly reactive alkali metal. It reacts vigorously with water, oxygen, and even moisture in the air. This reactivity makes it dangerous to handle and store in its pure form.
* Prevents Oxidation: Liquid paraffin, a mixture of alkanes, is chemically inert and does not react with sodium. This protects the sodium from reacting with oxygen in the air, which would lead to the formation of sodium oxide.
* Prevents Reaction with Water: Paraffin is also hydrophobic, meaning it repels water. This is important because sodium reacts violently with water to produce hydrogen gas and sodium hydroxide, which is a dangerous reaction.
* Provides a Protective Barrier: The liquid paraffin creates a protective layer around the sodium, isolating it from the surrounding environment and preventing any unwanted reactions.
* Easy Handling: Storing sodium in liquid paraffin also makes it easier to handle and transport. The liquid paraffin provides a stable and safe medium for storing the metal.
In summary, storing sodium metal in liquid paraffin is a crucial safety measure that prevents it from reacting with the environment and ensures its stability and safe handling.
