Question

Name the chemical formula of sodium amalgam?

Answer 1

Hint: Sodium (atomic number $11$) is the $11$th element in the periodic table and belongs to the alkali metals category. In its natural state, it is extremely volatile. If left exposed in the air, it can catch fire or react severely with water.

Complete answer:
The chemical name of sodium amalgam is $NaHg$.It is an alloy of mercury and sodium.
As we know sodium is a very reactive element it is kept in kerosine. Since Sodium is very unstable, it always occurs as a combined form in nature. Here, it is combined with Mercury to form a substance called amalgam. The chemical formula of Sodium amalgam is $NaHg$.
Alloys, intermetallic compounds, and solutions (both solid and liquid solutions) with mercury as a main component are referred to as amalgams. As strong reducing agents with greater handling properties than solid sodium, sodium amalgams are frequently utilised in reactions. They have a lower reactivity to water and are frequently utilised as an aqueous solution.
In organic chemistry, sodium amalgam has been employed as a potent reducing agent that is safer to handle than sodium. It is used to convert aromatic ketones to hydrols. In the design of the high-pressure sodium lamp, a sodium amalgam is employed to provide sodium for the right colour and mercury for the lamp's electrical properties.

Note:
In the Chlor Alkali process, which is processed to produce Sodium hydroxide, and Chlorine through the electrolysis of Sodium Chloride solution, Sodium amalgam is obtained as the by-product of it.
