When it comes to storing sodium metal, one common practice among professionals is to keep it immersed in kerosene oil. This technique ensures the safety and preservation of the sodium. But have you ever wondered why sodium is stored in kerosene oil? Let’s explore the reasons behind this method.
The Nature of Sodium
Sodium is an extremely reactive element. When exposed to air or moisture, it rapidly oxidizes and forms a layer of sodium oxide or sodium hydroxide on its surface, which hampers its usefulness. In order to prevent this reaction, sodium needs to be stored in an environment that is free from both air and moisture.
Why Kerosene Oil?
Kerosene oil is an excellent choice for storing sodium due to its properties. Firstly, kerosene is a hydrocarbon, which means it doesn’t contain any water molecules. This absence of water eliminates the possibility of sodium reacting with it and forming sodium hydroxide, which is highly corrosive.
Secondly, kerosene acts as a protective shield by creating a layer between the sodium and the surrounding air. This prevents the sodium from coming into contact with oxygen and forming sodium oxide, which can also be harmful and reduce the effectiveness of the sodium. By keeping the sodium isolated from the air, kerosene maintains the purity and reactivity of the metal.
The use of kerosene oil as a storage medium also facilitates the handling and transportation of sodium. Since sodium is a soft metal with a low melting point, it can easily be cut, shaped, or manipulated for various applications. However, its reactivity makes it hazardous to handle. By immersing it in kerosene oil, professionals can minimize the risk of accidental reactions or explosions that could potentially occur if sodium comes into contact with moisture or air.
It is important to note that when using kerosene oil to store sodium, proper precautions must still be taken. Professional lab settings ensure that the storage containers are airtight and properly labeled to avoid any confusion. Safety protocols are put in place to minimize risks and protect individuals working with sodium.
In conclusion, sodium metal is stored under kerosene oil due to its reactivity and the need to prevent it from reacting with air and moisture. Kerosene oil provides a protective barrier, maintaining the purity and reactivity of sodium, while also facilitating its handling and transportation. This method ensures the safe storage and efficient utilization of sodium in various scientific and industrial applications.
