- Hg Definition
Hg is the chemical symbol for the element Mercury, also known as Quicksilver in Vietnamese. Mercury is a transition metal that belongs to group 12 of the periodic table, with an atomic mass of 200.59 and an atomic number of 80. Being a heavy metal, mercury has a unique molecular structure of Hg2, formed by the covalent bonding of two mercury atoms. Under standard conditions, mercury can form Hg2+ ions.
- Properties: Hg
2.1 Physical Properties of Hg
Mercury is a liquid at room temperature, has a bright silver color, and is odorless. A unique feature of mercury is its neutral pH level, meaning it is neither acidic nor alkaline.
2.2 Chemical Properties of Hg
Mercury is quite inert, rarely reacting with other chemicals.
- Common Chemical Equations Involving Hg
Despite being very inert, mercury can still participate in certain chemical reactions.
- Preparation of Hg
4.1 Lab Preparation of Hg
In the lab, mercury is typically derived from cinnabar, a natural mercury salt.
4.2 Industrial Preparation of Hg
In industry, mercury is produced by melting cinnabar in specialized plants.
