1. Reactivity with air: Sodium is highly reactive with oxygen and moisture in the air.
* It reacts with oxygen to form sodium oxide (Na₂O), a white solid.
* It reacts with water to form sodium hydroxide (NaOH) and hydrogen gas (H₂). This reaction is exothermic and can be explosive.
2. Reactivity with water: Even small amounts of water can cause sodium to react violently. The hydrogen gas produced can ignite, causing a fire or explosion.
3. Reactivity with other substances: Sodium is also reactive with many other substances, such as acids, halogens, and alcohols.
Inert solvents like kerosene or mineral oil:
* Prevent contact with air and moisture: These solvents are non-polar and do not react with sodium, forming a protective layer around it.
* Non-flammable: Unlike other solvents like ether or alcohol, kerosene and mineral oil are not flammable, reducing the risk of fire.
* Low reactivity: They are relatively inert and do not react with sodium, ensuring its stability.
In summary: Keeping sodium in inert solvents like kerosene or mineral oil protects it from reacting with the environment, preventing potential hazards and preserving its chemical properties.
