Physical Properties of Sodium
- The metal lustre on sodium is very intense. It closely resembles silver in terms of colour.
- When the temperature is normal, it is so malleable that fingers may press it into the shape of leaves.
- Sodium compounds tarnish more slowly than potassium compounds when exposed to air.
- In the air, sodium reacts with oxygen to generate sodium oxide, which then combines with water vapour to form a sodium hydroxide film.
Uses of Sodium
- Additionally, it is utilised in soaps, the purification of molten metals, sodium vapour lamps, and enhancing the structure of some alloys.
- Sodium is a component of sodium chloride, a key substance present in the environment that supports life.
- Making esters and producing organic molecules both depend on sodium.
- Glassmaking requires solid sodium carbonate.
