Hg2 2+
Mercury (I) ion
Hg2^2+ is the chemical formula of a bivalent cation of mercury, also known as mercury(I) ion. It is formed by the oxidation of mercury metal in the presence of an acid to form Hg22+ as a soluble salt.
The Hg2^2+ ion has two mercury atoms that are bonded together with a covalent bond. The structure of this ion is linear, with a symmetric bond angle of 180 degrees. Each mercury atom in the ion is surrounded by two negatively charged ions, which are usually chloride or iodide.
The Hg2^2+ ion is a strong oxidizing agent and is toxic to living organisms, including humans. It is used in some industrial processes, such as the production of chlorine gas and the extraction of gold from ore. However, due to its toxicity, the use of Hg2^2+ is becoming increasingly restricted.
In summary, Hg2^2+ is a bivalent cation of mercury that is toxic to living organisms and is used in some industrial processes. Its structure is linear with a symmetric bond angle of 180 degrees, and it is surrounded by negatively charged ions.
