What are the properties and uses for sodium?
Uses and properties Sodium is a soft metal that tarnishes within seconds of being exposed to the air. It also reacts vigorously with water. Sodium is used as a heat exchanger in some nuclear reactors, and as a reagent in the chemicals industry. But sodium salts have more uses than the metal itself.
What is the properties of sodium chloride?
Physical properties: Sodium chloride is a white crystalline solid with a density of 2.16 g/mL, and a melting point of 801 °C. It is also available as aqueous solutions of different concentrations, called saline solutions. Chemical properties: Sodium chloride is readily soluble in water and other polar solvents.
What Colour is sodium?
Sodium is a very soft silvery-white metal. Sodium is the most common alkali metal and the sixth most abundant element on Earth, comprising 2.8 percent of Earth’s crust.
What are the chemical properties of salt?
They are brittle, hard and crystalline solids. Salt is white, odorless and it has a salty taste. All potassium (K), ammonium (NH4+) and sodium (Na) salts are soluble in water (H2O). Nitrites, nitrates, and bicarbonates can be dissolved in water.

What are the properties of salt in chemistry?
Salt is a chemical compound with a number of interesting properties:
- Crystals or white crystalline powder.
- Transparent and colourless in crystalline form – rather like ice.
- Crystallises in the isometric system, usually in the form of cubes.
- Soluble in water (35.6g/100g at 0°C and 39.2g/100g at 100°).
What are 5 uses of sodium?
Sodium is used to descale metals.
What are some physical properties of sodium?
The Physical properties of Sodium are the characteristics that can be observed without changing the substance into another substance. Physical properties are usually those that can be observed using our senses such as color, luster, freezing point, boiling point, melting point, density, hardness and odor.
What are the properties for sodium?
The key properties of sodium are: It is highly reactive, reacting explosively with water. It is a silver-white metal having a waxy appearance. It is soft with a bright shiny surface, however as sodium reacts with oxygen in the air it becomes dull due to the formation of a sodium oxide (Na 2O) film.
What is description of the characteristics of sodium?
Sodium Appearance & Characteristics. Sodium is considered to be non-toxic. Contact with the skin may, however, cause irritation and burns. Characteristics: Sodium is a soft, silvery-white metal . It is soft enough to cut with the edge of a coin. Freshly cut surfaces oxidize rapidly in air to form a dull, oxide coating.
