where is sodium used?
Answers
Answer:
Uses of Sodium
Sodium is used to descale metals. This gives the metal a smooth surface.
Sodium metal is also used to refine metals (such as zirconium and potassium) from their compounds.
Molten (liquid) sodium is used as a coolant in many nuclear reactors. It can be used on its own or can be combined with potassium.
Sodium is added to fatty acids to make sodium salts. These are much harder (with higher melting points) than potassium soaps.
The sodium fusion test uses the high reactivity, high solubility and low melting point to determine the presence of halogens, nitrogen and sulfur in a sample.
Sodium can be used as a reducing agent- changing some organic molecules into new forms.
Sodium vapor lamps (often used in street lights) are a very efficient way of producing light from electricity. These lamps give off a very distinctive yellow-orange color.
Sodium chloride is an important heat transfer material.
Sodium can be used alone or with potassium to dry solvents (called a desiccant).
