To distinguish Hg2CI2 from the HgC12 is by looking at the small manufacturer design differences or by checking the software numbers in the settings section.
Examples: HgO, HgCl2, Hg2Cl2, HgI2, etc.
HgCl2 - mercury(II) chloride. Hg2Cl2 is mercury(I) chloride
Hg2Cl2
Mercury (II) chloride is soluble, but Mercury (I) (mercurous) chloride is insoluble. The formula of the first compound is HgCl2, and mercurous chloride is Hg2Cl2. Also, lead chloride (PbCl2) and Silver chloride (AgCl) is insoluble. All other chloride solutions are soluble.
In HgCl2, mercury's oxidation number is 2+ and chlorine's is 1-.
There are two chlorides of mercury Mercury I chloride: Hg2Cl2 Mercury II chloride: HgCl2
Examples: HgO, HgCl2, Hg2Cl2, HgI2, etc.
There are two chlorides of Mercury Mercury I chloride: Hg2Cl2 Mercury II chloride: HgCl2
The formula is HgOH because Mercury is a transition metal and has an unknown charge until paired with hydroxide which has a -1 charge so they would combine equally to make HgOH
HgCl2 - mercury(II) chloride. Hg2Cl2 is mercury(I) chloride
S2Cl2 = disulfur dichloride, Cl-S-S-ClHg2Cl2= mercury (I) chlorideThe mercury (I) cation is Hg2^2+. It is sort of a diatomic ion. In the +1 oxidation statethere is no single Hg. In other words, HgCl does not exist. HgCl2 does exist, except in this case, mercury is in the +2 oxidation state.The only thing you have to remember is that there are no single mercury (I) ions, mercury (I) exists as Hg2^2+.I don't think Hg2Cl2 will be very ionic, what with an electronegativity difference of 1.16. That translates to a percent ionic character of 28.6 for the Hg-Cl bond.Hg2Cl2 would NOT be named mercury chloride. Mercury requires a Roman numeral in the stock system.Or you could name Hg2Cl2 as mercurous chloride.
