Properties of Sodium Metal
Sodium (Na) is a soft, silvery-white, and highly reactive metal. It can be cut with a knife and has a low density, making it one of the lightest metals. Sodium reacts vigorously with water, producing hydrogen gas and sodium hydroxide, which can be hazardous. It has a melting point of 97.79°C and a boiling point of 883°C.
Physical Properties
- Appearance: Silvery-white metal
- Density: 0.97 g/cm³
- Melting Point: 97.79°C
- Boiling Point: 883°C
Chemical Properties
- Reactivity: Highly reactive, especially with water
- Oxidation: Reacts with oxygen to form sodium oxide
- Flammability: Releases flammable hydrogen gas upon contact with water
Applications of Sodium Metal
Sodium metal finds applications across various fields, including:
1. Chemical Industry
Sodium is used as a reducing agent in organic synthesis and plays a vital role in producing sodium compounds like sodium carbonate and sodium hydroxide. Companies like Carolina Chemical and ATT Advanced Elemental Materials provide sodium metal for industrial applications.
2. Electronics
High-purity sodium is essential in the electronics industry, particularly in the production of semiconductors and solar cells. Suppliers such as Luciteria and Lab Alley offer high-purity sodium suitable for these applications.
3. Nuclear Reactors
Molten sodium is used as a coolant in certain types of nuclear reactors due to its excellent heat transfer properties. This application underscores the importance of sourcing high-purity sodium from reliable suppliers.
4. Educational Purposes
Sodium metal is frequently used in educational settings for demonstrations and experiments to illustrate chemical reactions. The Science Company provides sodium metal in various forms, making it accessible for educational use.
Safety Considerations
Handling sodium metal requires strict adherence to safety protocols due to its reactive nature:
1. Storage
Sodium metal should be stored in airtight containers, preferably under mineral oil or inert gases, to prevent oxidation and moisture exposure. It is crucial to keep it away from water and any oxidizing agents.
2. Handling
Always wear appropriate personal protective equipment (PPE), including gloves, goggles, and lab coats when handling sodium metal. Due to its flammability, ensure that all work with sodium is conducted in a fume hood or well-ventilated area.
3. Emergency Procedures
In case of contact with water or moisture, sodium can ignite spontaneously. Familiarize yourself with emergency procedures, including the use of Class D fire extinguishers, which are specifically designed for metal fires.
