Mercury(II) oxide, also called mercuric oxide or simply mercury oxide, is the inorganic compound with the formula Hg O. It has a red or orange color. It has a red or orange color. Mercury(II) oxide is a solid at room temperature and pressure.
Mercury(I) oxide, also known as mercurous oxide, is an inorganic metal oxide with the chemical formula Hg 2 O. It is a brown/black powder, insoluble in water but soluble in nitric acid . With hydrochloric acid , it reacts to form calomel, Hg 2 Cl 2 . [ 4 ]
2 ion, found in mercury(I) (mercurous) compounds. The existence of the metal–metal bond in Hg(I) compounds was established using X-ray studies in 1927 [2] [page needed] and Raman spectroscopy in 1934 [3] making it one of the earliest, if not the first, metal–metal covalent bonds to be characterised. Other mercury polycations are the linear ...

Mercury oxide can refer to: Mercury(I) oxide (mercurous oxide), Hg 2 O; Mercury(II) oxide (mercuric oxide), HgO; See also.
The one acetate group that remains on the mercury atom can be displaced by chloride: [7] C 6 H 5 OH + Hg(O 2 CCH 3) 2 → C 6 H 4 (OH)–HgO 2 CCH 3 + CH 3 CO 2 H C 6 H 4 (OH)–HgO 2 CCH 3 + NaCl → C 6 H 4 (OH)–HgCl + NaO 2 CCH 3. The first such reaction, including a mercuration of benzene itself, was first reported by Otto Dimroth in 1898 ...
Calomel is a mercury chloride mineral with formula Hg 2 Cl 2 (see mercury(I) chloride). It was used as a medicine from the 16th to early 20th century, despite frequently causing mercury poisoning in patients. [5] The name derives from Greek kalos (beautiful) and melas (black) because it turns black on reaction with ammonia. This was known to ...
Mercury exists in three oxidation states: 0 (elemental mercury), I (mercurous mercury), and II (mercuric mercury). Mercury emissions to the atmosphere can be primary sources, which release mercury from the lithosphere , or secondary sources, which exchange mercury between surface reservoirs. [ 2 ]
