I Am A Silvery White Metal Used To Make Salt

I am a silvery white metal used to make salt – Sodium, a silvery-white metal, plays a crucial role in the production of salt, a ubiquitous substance essential for life. Its unique properties and widespread applications make it a vital element in various industries and scientific fields.

Sodium is a highly reactive alkali metal with a low melting point and a distinctive silvery-white luster. Its atomic structure, characterized by a single valence electron, imparts its exceptional chemical reactivity. Naturally occurring in various mineral forms, sodium is primarily extracted from salt deposits or brine solutions.

Identification and Properties

Silver is a silvery white metal with a lustrous appearance. It is a noble metal, meaning it is resistant to oxidation and corrosion. Silver is a soft and malleable metal, making it easy to work with and shape. It is a good conductor of electricity and heat.

Silver has an atomic number of 47 and an electron configuration of [Kr] 4d ¹⁰5s ¹.

Physical Properties

Density: 10.49 g/cm ³
Melting point: 962 °C
Boiling point: 2162 °C
Hardness: 2.5 on the Mohs scale

Chemical Properties

Silver is a noble metal, meaning it is resistant to oxidation and corrosion.
Silver reacts with sulfur to form silver sulfide, which tarnishes the metal’s surface.
Silver reacts with nitric acid to form silver nitrate, which is used in photography.

Occurrence and Sources

Silver is a relatively rare metal. It is found in the Earth’s crust in ores such as argentite (silver sulfide) and cerargyrite (silver chloride). Silver is also found in native form, meaning it is found as pure metal. The largest silver mines are located in Mexico, Peru, China, and Bolivia.

Extraction and Refining

Silver is extracted from ores using a variety of methods, including:

Cyanide leaching: This method involves dissolving the silver ore in a cyanide solution. The silver is then precipitated out of the solution using zinc or aluminum.
Fire assay: This method involves heating the silver ore in a furnace to melt the metal. The silver is then separated from the other metals in the ore using a process called cupellation.
