Definition of Hg2O
Hg2O, also known as Mercury(I) oxide or mercurous oxide, has a molar mass of 417.63 g/mol. The molecule consists of two mercury atoms and one oxygen atom. In nature, Hg2O exists as ions with a structure of [Hg-Hg]2+ and O2-. -
Properties of Hg2O
2.1 Physical properties of Hg2O
Hg2O is a solid with a light yellow color. This substance is odorless and its pH level is difficult to determine because it is insoluble in water.
2.2 Chemical properties of Hg2O
Hg2O decomposes when exposed to sunlight or high temperatures, producing mercury and oxygen. -
Common chemical equations involving Hg2O
The common reactions involving Hg2O mainly involve the transformation into mercury and oxygen. A notable example is the natural decomposition of Hg2O when exposed to sunlight or when heated.
Hg2O -> 2Hg + O2 -> -
Synthesis of Hg2O
4.1 Laboratory synthesis of Hg2O
To synthesize Hg2O, a solution of mercury(I) nitrate is commonly reacted with a sodium hydroxide solution.
2HgNO3 + 2NaOH -> Hg2O + 2NaNO3 + H2O
4.2 Industrial synthesis of Hg2O
In industry, Hg2O is commonly synthesized by heating mercury in air.
