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. Mercury (II) oxide is a solid at room temperature and pressure. The mineral form montroydite is very rarely found.
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] Mercury (I) oxide is toxic but without taste or smell.
Mercury battery "РЦ-53М" (RTs-53M), Russian manufactured in 1989. A mercury battery (also called mercuric oxide battery, mercury cell, button cell, or Ruben-Mallory[1]) is a non-rechargeable electrochemical battery, a primary cell. Mercury batteries use a reaction between mercuric oxide and zinc electrodes in an alkaline electrolyte.
Hydroxides of mercury are poorly characterized, as attempted isolation studies of mercury(II) hydroxide have yielded mercury oxide instead. [58] Being a soft metal, mercury forms very stable derivatives with the heavier chalcogens. Preeminent is mercury(II) sulfide, HgS, which occurs in nature as the ore cinnabar and is the brilliant pigment ...

Several common mercury compounds are indeed red, such as mercury sulfide (from which the bright-red pigment vermilion was originally derived), mercury(II) oxide (historically called red precipitate), and mercury(II) iodide, and others are explosive, such as mercury(II) fulminate. No use for any of these compounds in nuclear weapons has been ...
Mercury(I) chloride is the chemical compound with the formula Hg 2 Cl 2. Also known as the mineral calomel [4] (a rare mineral) or mercurous chloride, this dense white or yellowish-white, odorless solid is the principal example of a mercury(I) compound. It is a component of reference electrodes in electrochemistry. [5] [6]
Mercury polycations are polyatomic cations that contain only mercury atoms. The best known example is the Hg2+. 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 ...
